I volunteer at a Florida wildlife rescue and someone brought in a squirrel which she had for about 1 1/2 years as a pet. The squirrel has turned aggressive so she gave it to us. Is is possible to "wild up" the squirrel and release it? I have a big cage in my yard and was thinking about putting it in with another squirrel which I've had as a baby. This squirrel will be ready to release in 3-4 weeks. Could I put them together for a couple of weeks and release them together?
