The living habits of squirrels
Squirrel's ears and tail very long hair, can adapt to the tree of life; they use a long hook like claws and its tail hanging on the branches. At dawn and evening, will leave the tree to the ground on the prey. Squirrels in the fall to find abundant food, both will make use of tree holes or dig holes in the ground, storing fruit and other food, while blocking the hole with soil or leaves. Body hair red squirrels in summer, the fall will be replaced with black and gray winter hair tightly cover the whole body. Newborn squirrel, hairless body, eyes are also unknown, eight days after birth, began to long hair, which opened his eyes after 30 days, 45 days can eat the fruit of stiff, actions become very agile. Squirrel is a very gentle little fellow masters, we should treat them gently, so that you are dead _set_ it will definitely not hurt you with his teeth. Of course they will bite you with his teeth, fingers gently, and you play, the feeling will be very itchy, this is it your friendship. Squirrel nest in the dense branches, or use of crows and magpies nest of waste, and sometimes also nest in tree holes; they are in addition to eating wild fruits, but also eat twigs, buds, leaves, and insects and bird eggs . One to fall, squirrels began to store food, a squirrel would often store a few kilograms of food a few hours, and sometimes see squirrels in the trees drying food, let them rotten bad. Thus, in the cold winter, squirrels do not worry about what to eat. Squirrel extremely well developed sense of smell, it can accurately identify the real pine nuts, empty, any pine cone tip to give the seeds to be squirrel-free kernel, although this does not bite open the seed shell, squirrel or a smell glance. There are squirrels store food instinct, autumn pine seeds are ripe, mouth with pine squirrels ran swiftly transported to a safe place to hide, a few or a dozen grain pile, buried in the ground, reserved for winter food. Although the land was covered with snow in winter, but the squirrels can still effortlessly find the hidden food, there are omissions can not find the individual. However, because of missing buried pine seeds can not find it helps to spread and spread and promote the natural regeneration. Squirrels are widely spread, almost throughout the entire forest. Quantity of its population, depends largely on the abundance of food less. If several years of food abundance, population size will be significantly increased, especially in the pine harvest year, the squirrels are living into the field to help gang migration to the _set_tled, the second year of situ breeding, and thus the increasing number; If this region pine harvest, squirrels would find another family to move between habitats, leading to dramatic reduction in the region. With the abundance of this squirrel food apologized to determine the behavior of populations, it is better skill, which not only multiply but also to aid in species populations are widely distributed. Although squirrels are rodents in a larger size, because it is not in the top of the food chain, so it is still threatened by predators, one is carnivorous birds of prey, such as sable, Hong Ferret, green ferret, weasel, yellow weasel etc., and owls, golden eagles and so on. Another major magpies and crows, which during the breeding season, start of squirrel pups. Former enemies from a sense of good breeding squirrel population health, because the large predators that hunt down all the old, weak, ill and. The latter is detrimental to natural enemies. Not only is the image of the squirrel cute, more importantly, the economic value of well-known squirrel. Squirrel skin has always been one of Heilongjiang Province, the bulk of wild fur, the past is an important export product. Do squirrel skin fur coat, scarf, hat, tail hair brush, etc. can be prepared. In recent years, the Hong Songlin reduced, leading to the red squirrels which feed on pine decline, the squirrel population is also reduced. At present annual output of less than 20,000 squirrel skins, history, highest at 185,000, we can see, the number of squirrels have been rare, should take measures to strictly protected.

Breeding habits of squirrels
Squirrel about 1,2 months every spring, estrus, estrus approximately two weeks. Squirrels began breeding-age period of 8 to 9 week old female, male is 9 to 10 weeks of age. On the squirrel, the fall also has a heat. In the non-breeding season, male and female adults occupy a certain place, respectively, as their scope of activities of life. In the wild, female protection of a certain area of the site is to protect the food, the other within the same individuals are not allowed to enter, for males as well. But in the breeding season, it is obvious that the scope of the protection area to relax, allowing the male to enter. Estrus, the female individual loss of appetite, activity strengthened, irritability, was excited states; sometimes lick the vulva, and frequent urination, and issued a pointed call to allow individuals close to the male; now become darker in color and swollen vulva, sometimes white or yellow mucus, or curd-like discharge outflow. Conditions in captivity for breeding, be sure to _select_ able-bodied, good gloss coat, a good mental state, the individual appetite. The requirements of the sexually active male mating ability; while females require strong maternal instinct, the number of multiple births, milk yield sufficient individual. When mating with one male and one female or one male and many females in the mating, pregnancy, the time the squirrel is about 35 to 40 days, 4 by early lactation, litter size about 3 times per year, each 4 to 6 yields up. As long as food is abundant, females can reproduce the squirrel more individual, with strong productivity. Cubs born at the beginning to the mother's milk as the source of all the nutritional needs, therefore, should pay special attention at this time the mother's nutritional status, when the squirrel just gave birth to small, could not see anything, development is slow, gave birth to nearly 30 days opened his eyes; to one and a half, the little squirrels before they are willing to outdoor activities. Eyes will be opened in a small squirrel is not open, the hold keeping squirrels away from home, become intimate with people. Suction feeding initially hot milk (30-40 ° c), 3-5 times per day. Bread soaked in milk gradually changed, or other soft food. Even though only after long into farming, as long as the patience to train slowly, and people will be very close, who climbed to the owner.

The type species of squirrels
According to the different living environment, squirrels Section is divided into tree squirrels, ground squirrels and rock squirrels. 35 is the world's nearly 212 Chinese, 11 genera and 24 species, including rock squirrels and rock squirrels 2 side profile is unique to animals. Many different types of squirrels, there are about 240 species around the world, China has 26 species. Where the squirrels live in the woods, in our country are very common throughout the Northeast and North China, which is also called the common squirrel. Its slender body, body hair is gray, dark brown or red brown, so also known as gray squirrels. There are three common squirrel: 1, the red belly squirrel: Red Squirrel, also known as "squirrel", mountainous areas is also called "hanging mouse." Is a medium-sized arboreal squirrels. Size: 19 ~ 25 cm Weight: 280 ~ 420 g Features: kiss short, small, round ears, thick neck Red belly squirrel mainly inhabit in the jungle, living habits and squirrel somewhat similar, more hi morning, dusk activities, feeding mainly on feeding a variety of nuts, such as pine cones, nuts and berries, mainly, but also eat a variety of leaves, tender branch, bud, and bird eggs, nestlings and insects. 2 times a year breeding, each producing 3 to 4 Aberdeen, Aberdeen majority of 2. 2, the long kiss squirrel: Long kiss Squirrel also known as "Red-billed squirrel." Size: 20 ~ 25 cm Characteristics: slightly shorter limbs, tail slender, short, fluffy tail hair, back hair and gray brown to gray chest hair Squirrels usually live a long kiss in the jungle, the habits of squirrels in general have little difference, but not entirely arboreal, often to the ground, fallen trees and weeds feeding, morning, dusk hours of the most active. 3, rock squirrels Rock squirrel, also known as "stone rats", "mop-up child", shape somewhat like the red belly squirrel.

Rock squirrels are habitat areas in the mountains, rock, rock squirrels can climb in trees though, but still rocks the main habitat, usually nest in Yanxi room. Rock squirrel activity during the day, mainly in the wild feed on fruit or seeds, such as nuts, walnuts, apricots, etc., but sometimes food crops, is a mountain forest pest. Other types of Chipmunk Size: Body length about 12 cm tail 15cm Origin: Northeast Asia, Hokkaido Eating habits: omnivorous plant-based Vertical bar pattern back hundreds of small squirrels. Just a small squirrel nest, if fed separately with the parents, it is easy to domesticate. The action quickly, while it should be noted that when fed to escape. The higher the cage to be prepared, as well as to avoid the lack of exercise, smoking cage wheel vehicles should be prepared to play sports squirrels. At the same time to install nest boxes. As a hiding place, in nature there is the phenomenon of hibernation, if kept in a warm room, that do not need to hibernate. Because less heat, summer cage should be well-ventilated place to move. Shrimp 夷松 rat Size: body length of about 20cm tail 25cm Country of Origin: Hokkaido Eating habits: omnivorous plant-based Distributed in Hokkaido, Japan, is located in the south of Honshu, Japan subspecies of the Japanese squirrel, squirrel size slightly larger than Japan. Summer and winter coat will change. In winter, the back is gray, belly is white, ears are long hair; summer, the body is light reddish brown, the ear is not hairy. Chipmunk feeding the same way, due to larger size, require large, sturdy cage. Do not need to hibernate in winter, as usual activities. Prairie dog Size: body length of 30cm 8cm long tail Origin: North America Eating habits: omnivorous plant-based Body color from yellow to brown both. Chunky body, coupled with a short tail. Groups live in the grasslands in the mining of the acupuncture points of each other interlinked. Social life of habit, even if keeping more than just not fighting. In the ecological films often, is very popular cute animal. In particular, the action is to stand and sit down, especially cute, and very vulnerable to domesticate. At the same time as the dog-like tail swing, it is endearing. Plant-based foods, hamsters and other artificial feed and dog food is also a good choice. Although the market has sold in pairs, but the breed is still very difficult. Small Japanese flying squirrel Size: Body length about 12 cm tail 15cm Origin: Asia Eating habits: omnivorous plant-based Back to gray-brown, belly is white. Film is connected between the limbs, glide in the air after opening. Nocturnal animals, unique eyes, looks very cute. Mainly at night, is the most suitable pet food pet owls. Use of nest boxes for bird cages, used for sleeping during the day. Domesticate, the glider can be put inside the house came out outside. The same family with the squirrel, the way farming methods to cf. And the usual fruit-eating squirrels in the artificial diet, and occasionally feeding a number of animal food.

Squirrel Feeding Management
First, the construction and preparation of farm homes Squirrel is a separate case in the wild life, so to provide the environmental conditions, should allow them to have enough single-habitat conditions, they can contact with each other in order to facilitate reproduction. (A) sheds conditions (B) Sports Ground conditions Direct and open sheds similarities, an area 36 meters long and 3 meters wide, 3 meters high. Three sides and roof are in fine wire mesh of not more than 1.5 cm is appropriate. Network around 20 cm from the ground below the walls. Equally suitable place from 1 to 2 dead tree branches, concrete floor. Second, breeding management and reproductive technologies (A) feed Can be fed pine nuts, hazelnuts, melon seeds, sunflower, pear, apple, and different regions according to the season as far as possible with a variety of feed they choose. Feed can be divided into several parts placed so that they are fighting for the dry material can be 2 to 3 days add 1, supply of fruit a day to day is better eating. Basin to water at any time. (B) Management Summer is hot, you can observe the performance of animals, if necessary, add temporary playground mats or bamboo mat ceiling shade, spray water cooling. Winter may not have insulation measures be taken. (C) Propagation Techniques The introduction of animals to be _select_ed as breeding robust physique, male and female ratio can be 3 to 4:1. Singled out the weak, especially the frail male, other males may be affected by the attacks. In the breeding season may be to some animal foods such as cooked eggs, bread and so on, to see whether they like it. Also in the circle and put some clean leaves, crushed hemp, twigs, etc., for their nests or nest pad use. The cubs were born six months, to separate the single-support, so that the density is too large. Third, diseases and natural enemies control Because squirrels in captivity conditions, a small number, less affected by attention, and not easy to observe, so it is not suffering from a disease of the report. But they belong to teeth gnawing animals, the beam may pass the plague, it must improve health every day, regular disinfection. In addition, the sheds and playgrounds to prevent drilling voles and rats, resulting in snatch feed, damage and spread diseases such as squirrels. IV. Feeding Management Squirrels seem to Fagaceae feeding on the seeds, but also in nature a lot of insect eating, so some of the best animal feed also the food. Walnuts, chestnuts and other nuts are a favorite food, open bite hard shell, the squirrel is not only the game, you can also help wear teeth. Often the best kind of food fed. If the artificial diet staple food, but also to add other foods such as apples. Good feed and scientific management is to ensure the squirrel important condition for normal growth and development, but also to improve production capacity and improved varieties of squirrels conditions. Special attention should be feed with a ratio of protein content and quality. Fed a mixed feed squirrel feed, forage and green succulent feed. Generally mixed feed barley, wheat, corn, soybeans and models composed of skin, content of 25% barley or wheat, 20% corn, 15% soybean meal, 10% soybean, 20% bran, 6% fish meal, bone meal and 3% 1% salt, the mixed feed, the nutritional composition: 20% of the protein, 6% fat and 42% carbohydrates. Roughage are peanuts, sunflower, and walnut; green succulent feed has cabbage, carrots, rape, mulberry leaves, holly leaves; summer and fall can also be fed one o'clock the food like fruits such as cucumbers, tomatoes and watermelons. Fed each day to feed squirrels of approximately: 30 grams of mixed feed about 200 to 250 grams of crude feed, and the green succulent feed 150 to 200 grams. Daily in early, middle and late fed three times a day feeding point of fixation is necessary. For the young squirrel, necessary to appropriately increase the frequency of feeding, feeding at any time and to ensure that it meets its growth and development of energy and nutrition needs. At different times, squirrel food have different nutritional needs change. In female squirrels, during pregnancy, lactation feed should be diversified, and as far as possible feed fresh, nutrient complete, the fetus or pups to meet the nutritional needs of growth and development, in particular, to improve the dietary protein composition. Pups at different developmental stages, feeding should be noted that when the composition of food and nutrition. Male squirrel in the breeding period, convalescence, but also to enhance nutrition, and more to increase fish meal, milk supply; but be aware that if the supply of carbohydrates in excess of feeding standards, the squirrels will cause physical deterioration of the performance of their young affect its rate of growth and development. Squirrel must pay attention to clean drinking water in summer to frequently change the water in winter to avoid drinking Bingdong Shui, thus reducing the adverse physical and infectious animal diseases. Fifth, rearing environment Squirrels are very active, particularly fond of climbing trees, more three-dimensional space, should try to use a broad and high cage. Habit of nesting in the trees as squirrels, nest boxes installed in the cage should be high. Bird nest boxes can be used with the entrance at the height of the nest boxes instead. Squirrel moves very quickly, switch to the attention of the door, to avoid Chenxi escape. In case of escape, if a sudden force to seize, to avoid being bitten by squirrels. Squirrels are large-scale farming. In this case, to a greater demand for pet homes, into sports and animals rest, sleep two parts of the premises. In the sports venue, or placement of trees to be planted for the squirrels jumping climbing perch. Female and male non-breeding of adult squirrels to be separated during the breeding as well. If it is reserved for breeding, the squirrels should be given special care, and can be fed separately. Keeping caged pets than any other single individual to a large number of the area to ensure it has sufficient amount of exercise, can the size of 90x30x45 cm, have a bearing cage bottom plate dung for cleaning and disinfection. Each pet feeding bowls have to be placed within the frame and water basins, and fixed them to avoid being thrown to the dirty or wet their environment; bowl can be used enamel pots or plastic Xiaopen. Although squirrels living in cold temperate needle. Bars mixed broad-leaved forest zone, but because of its superb nesting technology, the nest temperature is much higher than the nest, so the artificial breeding conditions for the winter to ensure their safety, the general to maintain the temperature of 5 ~ 23 degrees Celsius not too low, otherwise it will affect their fertility and reproduction capacity. Sixth, other issues Squirrels seem to Fagaceae feeding on the seeds, but also in nature a lot of insect eating, so some of the best animal feed also the food. Walnuts, chestnuts and other nuts are a favorite food, open bite hard shell, the squirrel is not only the game, you can also help wear teeth. Often the best kind of food fed. If the artificial diet staple food, but also to add other foods such as apples. Good feed and scientific management is to ensure the squirrel important condition for normal growth and development, but also to improve production capacity and improved varieties of squirrels conditions. Special attention should be feed with a ratio of protein content and quality. Fed a mixed feed squirrel feed, forage and green succulent feed. Generally mixed feed barley, wheat, corn, soybeans and models composed of skin, content of 25% barley or wheat, 20% corn, 15% soybean meal, 10% soybean, 20% bran, 6% fish meal, bone meal and 3% 1% salt, the mixed feed, the nutritional composition: 20% of the protein, 6% fat and 42% carbohydrates. Roughage are peanuts, sunflower, and walnut; green succulent feed has cabbage, carrots, rape, mulberry leaves, holly leaves; summer and fall can also be fed one o'clock the food like fruits such as cucumbers, tomatoes and watermelons. Fed each day to feed squirrels of approximately: 30 grams of mixed feed about 200 to 250 grams of crude feed, and the green succulent feed 150 to 200 grams.

Squirrel control treatment
1, teeth too long Long-term consumption of soft foods, teeth grinding and gnawing too long can not be normal growth. Excessive growth of teeth inside the mouth will hurt and affect food intake. There will also be complicated by corruption and gums, rhinitis and other symptoms. This will result in the gradual loosening of teeth, and fall. Side of tooth loss, the other side of the teeth grinding due to lack of normal rodents, need regular cutting operation. Early diagnosis, early treatment is expected. 2, fighting the damage caused Squirrel groups to attack the weak habits. Appearance seemed to be healthy, but the squirrels have been seriously ill, the attack will be met with healthy squirrel. If the anatomy of the death of the squirrels being attacked, has long been suffering from serious illness will be found. In addition, the frail squirrels, are also vulnerable to attack. Found that squirrels fighting, cage should be separated with each squirrel. The site of injury, antibiotic treatment, so the wound fester; large wounds should be surgical suture. Kill each other because of the possibility of weak isolation squirrels as soon as possible. 3, hypocalcemia Prenatal and postnatal female squirrel will suffer from the disease. As the concentration of calcium in the blood decreased, while the convulsions, paralysis, ataxia and other symptoms. Then if an early injection of calcium, there will be consideration of death. In pregnancy and the postpartum lactating female squirrels in the diet to add calcium, as a preventive method. In addition, the sun is also important. 4, rickets Squirrels as mankind in general, will suffer from rickets. In addition to regular activity of calcium and vitamin d, the sun is also indispensable. The effect of the use of artificial tanning is good, but the wavelength of ultraviolet light can cause serious burns properly, so before use, it is best asked in detail about the hospital. 5, urethritis The formation of urinary tract infections by bacteria urethritis. As the penis enlargement male squirrel, dysuria may also occur. Generated when the urination pain, will issue a cry of pain. If you find these symptoms should immediately urine, the use of appropriate antibiotic therapy. 6, fracture When the squirrels play in the house, it may occur due to improper jumping fracture. Simple fracture, as long as the hospital in accordance with the instructions, can be cured without surgery. Squirrel intolerance anesthesia, it is best to avoid surgery. However, if the injured spine, the prognosis may be poor. 7, mite disease 8, pneumonia 9, gastrointestinal tympanites 10, vitamin c deficiency

Squirrel Of: Gianluigi Buffon (the famous 18th century French naturalist writer / forward to the <"Natural" A History "36 / The End for time: 40 years - from grade 5 on the List of Fujian Education) The squirrel is a pretty small animals, docile, cute, very likable. They are delicate and pretty face, eyes glistening, supple body, limbs light, very quick, very alert.

It is said that when the squirrel over the water, with a piece of bark as a ship, with its own tail as a sail and rudder. Unlike Shanshu squirrel winter hibernation, as one does not move. They are very alert, as long as someone touched a little bit at the roots, they came out from the nest, hiding under tree branches or other trees to escape. Very light running and jumping squirrel, always small jumping forward, sometimes scampering. Their claws are so sharp, the action is so quick, a very smooth high tree, dived on the climb went.
