My boy kitty is fine with my buns but my girl kitty will still bop them if they try to hop right up to her. It's funny they both know this now and pretty much stay clear of Bean. But Tyler - they just hop up to him, around him, whatever. They know he won't smack them.
And I know Bean doesn't hurt them. Ophelia looks a bit insulted but I don't think Oliver cares much at all.
I do wish they would snuggle together. That would be really nice.
