We have lots of oaks, and lots of squirrels, no rats. They love to eat the aluminum ties from my chain link fence and eat holes in my water hoses. They dig in the beds and are a general nuisance, still they are cute. But I do wish I did not have so many of them. They do damage the tomatoes when they are getting ripe and they dig up the little seedlings, but over the years they seem to be getting better about staying out of the garden. It is about time for some new hoses I have had to patch the holes gnawed in them by the squirrels so many time.
