I'd hate to think how depressed my Angelboy would be if he didn't have other cats to play with and snuggle with! Kiri's on the other end of the spectrum--I don't think she'd mind being an only cat, but she has her own little hideaway next to my desk and she seems to like the arrangement.

Hagrid and Bob are buddies. They'll walk along side-by-side, rubbing against each other. Lily likes to snuggle with Katie or Angel.

I believe that, like most things in the feline world, it all depends on the cat!
