Well, Justus loves him, as he loves anything that breathes. Bella wants to play with him, but he's older and not in the mood, so he pops her on the head. Shelby has been taught to ignore cats, so she deliberately looks the other way when he walks by. Evie hates her. Evie hates everything.
Woody has only met him a couple of times, since he's been on shutdown. A play bow, tail wag, couple of barks, but when it was clear Percy wasn't going to play, he just walked off.
Percy is more of a people cat. He wants to be where we are at all times, is very vocal about wanting to be fed, and insists on sleeping between us, something that drives me batty. But he's really one of those truly great cats to have.
