I have four (see icom)! Vic tolerates them all, but never has any contact--exept with us; then he's a smoocher. He likes them though, and when the kittens were small, I could usually find them outside by finding Vic and looking where he was looking. :-)

Here's a shot with all four together (http://pics.livejournal.com/vilakins/pic/001xs7dr).

I have four because Jasmin really bonded to Claudia and not Vic, and Claudia has kidney disease, so I got Ashley to be her friend for life, as Tessa and Claudia were. Claudia still gets lots of cuddles as you can see, so it worked out well.
