I only squirt the kitties who own us. Ours are pretty well trained to stay in this yard and don't roam wild in the neighborhood. They just go out when we are with them. Yes, cats will train and learn. They are smart enough not to listen to us lots of the time, thought. The serious side? Yep, that is an issue from owners to abusers but "that" is one I don't think I can handle for a challenge entry. I have to keep my animal stuff on the happy side! : ) Tom.
