Precautions:

Squirrels have the habit of attacking the weak in the group. Squirrels that look healthy but are seriously ill will be attacked by healthy squirrels. If you dissect these squirrels that were attacked to death, you will find that they are already terminally ill. In addition, weak squirrels are also vulnerable. When squirrels are found fighting, each squirrel should be separated by a cage.

The injured part should be treated with antibiotics to prevent the wound from festering; For larger wounds, surgical suture should be performed. Because of the possibility of cannibalism, weak squirrels should be isolated as soon as possible.
