I don't mind squirrels. We have a walnut tree in our yard, and they pick up all the walnuts(literally thousands every year), and they have food all year long. They are fat, healthy little buggers! They tend to get a little aggressive some times. They will "bark" at you and slap the tree with their paws, but I throw walnuts at them, and they stop. I actually enjoy watching them eat the nuts. Very cute. Very messy, but cute!
I've lived in this house 15 years and they have never done damage(except they did steal my bird feeder once), and they don't bother my cat. I live in perfect unison with about 20 of them. And better them clean up thousands of walnuts than me!!
