I love them all I know they are destructive but it is a fight for survival and if it was me I would take advantage of the free food just like the birds and I would chew alittle to get a warm place to stay and protect my babies.I guess I look at it differently than other people I have hand reared a baby squirrel and I was suprised how loving and smart they are.The one we had used to gently bite us to go back in its cage so it could go to the corner and pee it never did that on us and when it saw us in the morning it purred like a kitten.We rehabed it and like to think it is still out there.Just wanted to add that we work closley with a wildlife rehab person so we are informed with how to look after wild animals properly
