We have 3 uniquely different cats, 2 males and 1 female.
The female doesn't cause much fuss or create problems except for the occasional hairballs, but you should see the long hair on this little lady you would understand that, "OK so a few hairballs are OK with the looks of her beautiful fur blowing in the wind is like a field of wheat on a windy day".
The boys however seem to battle over their territory often, I mean it's a daily thing. But alas, we caught them together in the same sleeping area, do they not know we would catch them eventually?!?
Ah Cats...
