We had three young fox squirrels that we raised from before they opened their eyes, all the way through winter. One of them was turning white and was the sweetest thing ever, the other two were demons and would bite you every chance they got. FYI... squirrel bites hurt!!!
About 2 weeks before we were going to let them go, the gas man came to fill our tank and apparently screwed up something because it leaked the gas out of the tank and into the room where we kept the squirrels. Luckily the cat wasn't back there that night.
We were going to keep the white one, he was entirely too tame to survive on his own.
