Notice that the people who insist neutering cats doesn't stop them from spraying all immediately afterward state they have more than one. Ta-da!!!

You may as well not bother fixing them if you're going to keep more than one. Cats do not share the litter box. One comandeers it and won't let the other use it or neither will use it.

Quite frankly, one cat per household is enough. I won't even date women who keep more than one. It tells you something--figure it out if you already haven't.

Cats are very clean but more than one in the same house becomes a pig sty. A friend of mine broke up with his girlfriend who had about 6 cats at least of all ages. His carpet was smelling funny and he tore it up from the floor. The sponge cushion thing underneath was COMPLETELY soaked in cat piss. Totally. Not an uncontaminated square inch.

My cat would never ever do that. He can't stand his shit and piss being all over the place. But then he's an only cat so he doesn't have to compete or force other cats to stay out his litter box.

I know some people love having cats all over the place but I recommend only one. That's quite enough.
