On a positive note, I've always had bunches of gray squirrels in my yard, some are decently friendly, but the other day, I noticed a very pretty red squirrel had moved in too. When we first moved in, there was a super friendly squirrel who would come right up to people. We called him Speak because he would chatter and speak to people (and it's a joke from the Tick cartoon). I never tried to pet him, but I fed him all the time. One time he came up to me asking (NEVER begged, just asked) for some food. I didn't have any nuts, what I normally gave him, so I went inside to see what I could find. All I had was bread heel piece. I came back out on the porch and he had left, so I just put it on the corner of the porch. I went back inside and went about my business. A few hours later, I went outside and the bread was gone, and in its place was a neat pile of green grass about 2-3" long, carefully stacked and arranged. Speak paid for his food.
