Hedgehogs can’t adjust their body temperature by themselves and can’t keep it at the same temperature, so they are heterothermophilic animals. They are afraid of heat, so they mainly live in Europe and northern Asia, and there are many in the north of China and the Yangtze River Basin.

Hedgehogs are omnivorous animals. Wild hedgehogs mainly prey on animals with soft spines or small spines and some wild plants such as grass roots, melons and fruits. Hedgehogs are naturally timid, like quiet places and don’t like lively places. They usually live in shrubs and jungles, so they usually go out to look for food at night.

They mainly eat insects and worms as their main food. They can eat about 200 grams of insects a night. For humans, they are a kind of beneficial animals, which can catch many pests and help agriculture. They have a long nose, so their sense of touch and smell are very sensitive. They also like to eat ants and termites. When they smell where there is food, they will dig a hole with their claws, and then put their tongue into the hole to turn around, and a rich meal will come to hand. They sometimes eat newborn birds, eggs, frogs and lizards, and they also eat crops when they are particularly hungry. Later, they were introduced there by new Zealanders. In New Zealand, they had no natural enemies, so they slowly overbred and became a disaster. Because they didn’t eat enough insects, they had to look for snails, earthworms and bird eggs to eat.

Hedgehogs are very gentle animals, so they are very popular in some countries and kept as pets. Because ordinary hedgehogs cannot be kept as pets, people combine ordinary hedgehogs with an African hedgehog called four toed hedgehog. The hedgehog raised in this family can be fed by itself, mainly with meat, vegetables, grain and some by-products, such as chicken, lean meat, carrots, cucumbers and so on; In addition, some fruits, nuts and small animals, such as caterpillars, beetles, snails, earthworms and so on; It is not sensitive to milk and hedgehogs. A mature hedgehog eats about 50 grams of food per meal. At the same time, it should make more varieties of feed. Too single will lead to their refusal to eat and fight with their companions.
