I have a western gray squirrel that I rescued 1 yr ago (female) as a baby. Do I need a rescue licence or certification to keep her? Animal control is asking questions about her. She is domesticated does not bite and is very loving. I'm her walking tree.

Here are websites you might be interested in.

Pets squirrels: feeding, care, cages, toys, health, veterinary care, exercise

I can't find if it is illegal or not but from what I can see there are so many varieties of squirrels and it looks like certain ones may be illegal.
