I don't have anyone in my house that treats my babies bad and never have. Just a sly comment from them like "The only good cat, is a dead cat" and they are not invited back. If someone came in and deliberately was mean, they would be asked to leave on the spot. That guy is a JERK and having his fun at your cats expense. Anyone who is mean to a animal will eventually treat humans the same way so stay as far away from him as you can!
