Gary gets along absolutely beautifully with people, and he seems to like almost all humans. Other felines? Well, we know he came from a situation where he was living with other cats, but we don't know much about that, and he doesn't seem to appreciate their company here. We've caught him bullying a couple of the other males, but only once in a while. So we're not sure what to tell you. It might be that he just needs time to settle down, as he's a fairly recent arrival here.
We'll keep you updated on Gary as he settles in more and more. If you think you might be interested in him, do come in to meet him. He really is a beautiful boy.
