Sorry if I wasn't clear.

I'm of course talking about all nuetered cats.
The rescue says it likes to place cats in mixed gendered households so there is less rivalry. I understand that all females is not a good situation, if you want your cats to be cuddly friends, but I never heard of that with males. Now, the spraying issue, Thanks God my two boys have never done it, but my two prior boy Tuxes did, later in life. They were only cats and I never figured out why.

I'd rather take their advice and get a female that have one of mine start spraying. But, I was just wondering what the opinion out there was on having all boy cats. And who, if anyone has had problems.
