Toby the cat and the Squirrels
The squirrels set out the alarm call when my cat approaches. He is a manageable threat but one that must be watched. Any let down of the guard and the cat could take advantage of it. The cat does not do this out of meanness or anger but out of instinct. He is a cat after all. He is a small animal terrorist. That is what he does and the other animals must watch out for him and other cats.
One of the tenants puts bird seed on the ground for the animals so the squirrels are pretty spoiled. It gives Toby the cat plenty of animal watching intrigue. Sometimes he just sits there and watches them. They seem to be aware of it, leery, but continue their business.
