Well Daniel,
The squirrels around my house will eat anything, old donuts, bread, rolls, crackers, and even old cat food !
If I had a squirrel that is eating at my house, I would sit outside, and when he made his move, take him OUT !
They chewed up some rodent proof wiring in my attic a few years ago, and it took me three days to evict 7 fury rodents, and after I closed up the small hole behind my gutters with galvanized steel sheeting, another one stopped by to see if he could move in, he had a severe case of lead poisoning shortly after I found out where the tink-tink-tink was coming from. :)
So Daniel, go GET ER DONE !!!!!
Bill
