The body functions are developing, but the limbs are not fully and systematically developed. Basically, it is a state of eating, sleeping and eating. The fetal hair on the body is almost incomplete, and the blood vessels and bare wrinkled skin on the stomach can be seen.
Squirrel 10~20 days:
At this point, the color of the squirrel's body has basically formed, covering the skin. The biggest feature is that it has begun to grope around and learn to explore unknown areas with its limbs.
Squirrel for 20~30 days:
By this time, the squirrel's coat color was already obvious, and the hair on its stomach began to appear, and its crawling speed became faster, and its eyes were already open. About 25 days, I began to open my eyes, but at this time my eyes could only see the general things. It takes 1~2 days to adapt to the environment. At this time, remember not to use strong light such as flash to illuminate its eyes, which are very fragile.
Squirrel 30 ~50 days:
Can eat cake, 45 days ago, they were still eating, sleeping and eating. From 45 days, most demons can eat melon seeds.
50 to 80 days:
Self-personality began to appear and continue to improve, with a tail opening rate of 50%. I began to be active instead of taking a nap. After eating melon seeds, my teeth began to turn yellow.
80 days to 4 months:
The tail has been completely opened, the teeth have begun to turn yellow, and the self-character has been completely cultivated.
As long as you are patient, you can still cook it if it is good for adults. If you are impatient, buy a small one!
Devil squirrel
Devil squirrel is a kind of squirrel, belonging to Eurasian red squirrel, also known as devil squirrel in folk. The devil squirrel is smart and active, and likes to be clean. When raising them, they should try to choose a wide and high cage so that they can enjoy themselves.
Features:
The tail hair is thick and fluffy, and the limbs and front and rear feet are long, but the forelimbs are shorter than the hind limbs. The ear shell is well developed, which can reach the eyes when folded forward, and there is a bunch of long black hair at the ear end in winter. The back of the whole body is brown-gray from the kissing end to the tail root, the sides and limbs of the body are brown-gray, the hair roots are gray-black, and the hair tips are brown or gray. The abdomen is white from the back of the lower collar to the tail root and the inside of the limbs. The back and ventral surface of the tail are brown-black, the hair roots are gray and the hair tips are brown-black. The snout, cheeks and lower protrusions are back color, but blue-gray, the ear shell is black-gray, and there is a large bunch of black tufts in winter. Individual coat colors vary greatly, such as cyan, gray, brownish gray, dark gray and dark brown. With the regional differences, the coat color also changes. For example, the coat color of Liaoning squirrels is gray, while the coat color of China southern squirrels is black. In addition, the coat color is also affected by the seasons. The coat color is gray or taupe in winter and black or dark brown in summer.
strange hobby
Squirrels have very long ears and tails, which can adapt to life in trees; They hang upside down from the branches with claws and tails like long hooks. At dawn and evening, they also leave the trees and hunt on the ground. After finding enough food in autumn, squirrels will use tree holes or dig holes in the ground to store fruits and other foods, and at the same time block the holes with dirt or fallen leaves.
In autumn, the devil squirrel will change into black and gray winter hair and cover the whole body tightly. The newborn squirrel has no hair and its eyes are unknown. They began to grow long hair eight days after they were born. Open your eyes in about 30 days, and you can eat thin-shelled nuts in about 45 days. The magic squirrel will become agile after more than two months. Squirrels are very docile to their owners, so we should treat them gently, so that they will be dead set on you and will never hurt you with their teeth. Of course, they will gently chew your fingers with their teeth, tease you and feel itchy, which is their friendly performance to you.
Squirrels nest in dense branches, or use abandoned nests of crows and magpies, and sometimes nest in tree holes; They eat not only wild fruits, but also twigs, buds, leaves, insects and eggs. As soon as autumn comes, squirrels begin to store food. A squirrel often stores several kilograms of food in several places, and sometimes sees squirrels drying food in the trees to prevent food from going bad and moldy. In this way, in the cold winter, squirrels have nothing to eat.
Squirrels have strong fertility. Squirrels, like other rodents, have the characteristics of precocity and rapid reproduction. From January to February every year, the male squirrel and the female squirrel begin to fall in love. The male mouse swings its thick tail and jumps into the canopy to chase the female mouse. At this time, the mother mouse is also very excited and enthusiastic. Estrus lasts about two weeks, during which the male and female are almost inseparable. Female rats give birth to babies at 35-45 days of pregnancy, usually giving birth to two babies every year and occasionally giving birth to three babies. Female rats born in the first year give birth to 3 -6 cubs per fetus, and 5-10 cubs per fetus after the second year. Newborn cubs are smooth and hairless, with red body and closed eyes. Weight 7-8.5g, body length 5.9cm and tail length 2.6cm.. Young rats begin to mature sexually after 8-9 months of birth, that is, they can reproduce with their spouses in the next year.
Squirrels are omnivores. Squirrels mainly feed on seeds and fruits of various grains, and occasionally eat some small insects. Its vegetarian diet is mainly Korean pine, spruce, fir, larch and Mongolian pine. Mongolian almond and hazelnut, acorn dried fruit and seeds; Carnivorous foods are mainly insects, larvae, ant eggs and other small animals. When the food is green and yellow, the squirrel has another choice. We eat tree buds in spring and berries such as mushrooms, trays and cranberries in summer. In autumn, food is extremely rich, and we can eat whatever we want, but the most popular is red pine nuts. Speaking of picking pine nuts, this is squirrel's specialty. No matter how tall the tree is and where the cones grow, squirrels can eat them. The specific process is: it first bites the mature cone to the ground and then comes down from the tree. Like primates, it pries open the cone scales with its front feet, bites open the seed coat, takes out the seeds and feeds on pine nuts. Interestingly, when the squirrel is frightened, it doesn't put down the food easily, but runs away with a cone in its mouth.
Squirrels have a developed sense of smell. They can accurately identify the empty seeds of pine nuts. None of the seeds abandoned by pinecone-topped squirrels have any seeds. Although the shells of these seeds have not been bitten open, squirrels can still smell them. Squirrels also have the instinct to store food. When the seeds of Korean pine are ripe in autumn, squirrels run around with pine nuts in their mouths and transport them to a safe place to hide. A few or a dozen are buried underground as food for winter. Although the earth is covered with snow in winter, squirrels can still find their hidden food without difficulty, and some of them are missing. However, it is precisely because it is buried underground that it has not been discovered, which contributes to the diffusion and spread of Korean pine seeds and promotes natural regeneration.
Squirrels are widely distributed, almost all over the forest. Its population depends largely on the richness of food. If there is enough food for several years in a row, the population will increase obviously, especially in the year when pine nuts are harvested, squirrels living in other places will migrate here in groups and breed in situ the next year, so the population will increase sharply; If there is no good harvest of pine nuts in this area, squirrels will have to move their families to find another habitat, resulting in a sharp decline in the number of squirrels in this area. The squirrel's behavior of determining the population size by the richness of food is indeed superior, which is not only conducive to population reproduction but also conducive to population spread.
Squirrels have different living habits from other animals. They like to be active in broad daylight, especially in the early morning. They often jump around between tree trunks and branches, foraging and playing for a while, unrestrained and uncomfortable. Squirrels have no habit of hibernating, but they are not very active in winter. Especially in severe winter, the time to leave the nest is short, usually around 9 am, which is 1 -2 hours; Come out for activities after 1 pm, and stay in the nest at other times. Squirrel has a habit. No matter how cold the weather is, it doesn't eat in its nest. Instead, it sits on a branch, facing the rising sun, puts food into its mouth with its forelimbs in its arms, chews and tastes it with relish, sometimes pricks up its ears to listen, and sometimes turns its eyes to look around, which makes people laugh.
Although the squirrel is one of the larger rodents, it is still threatened by natural enemies because it is not at the top of the food chain. One is carnivorous birds of prey, such as mink, ferret, weasel, owl, golden eagle and so on. The other is mainly magpies and crows, which attack squirrel cubs during the breeding season. In a sense, the healthy reproduction of the hostile squirrel population the day before yesterday is beneficial, because most of the natural enemies are old, weak and sick. The natural enemies of the latter are harmful. Squirrels are not only cute, but also widely known for their economic value. Squirrel skin has always been one of the main wild furs in Heilongjiang Province, and it was once an important product to earn foreign exchange through export. Squirrel skin can be made into fur coats, scarves and hats, and tail hair can be made into brushes. In recent years, due to the decrease of Korean pine forest, the output of Korean pine nuts for squirrel foraging has decreased, and the number of squirrels has also decreased. At present, the annual output of squirrel skins is less than 20,000 pieces, and the highest in history has reached 1.85 million pieces. It can be seen that the number of squirrels is scarce, and measures should be taken to strictly protect them.
Others:
April-May is the breeding season for chipmunks and Hokkaido squirrels, and they can produce 4-5 small squirrels at a time. Reproduction is similar to mice. When the little squirrel's eyes are about to open, if he stays away from the mother squirrel, he will become close to people and climb on his shoulders and head without care. Initially, hot milk (30-40℃) was fed through a straw, 3-5 times a day. Gradually change to bread or other soft food soaked in milk. Even if you start breeding when you grow up, as long as you train patiently, you will be very close to the people and climb on your master.
