How many cats is too many?

[Kayleighann]

Hi, we have 2 cats a male 6 and female 4. Both moggys both neutered. Both indoor cats. I have seen some persian kittens and am thinking of buying one.
Is 3 to many cats?
Will my 2 be ok I don't want anyone to start marking there territory!
My current 2 cats are not friends, they tolerate each other they don't fight but they sleep separate never get to close to each other but do eat nxt to each other.
Will bringing in another disturb the peace?
If I do is it better to get male or female or wud it not matter ?
Xx

There is never enough.

It was 4 for us too.
3 seemed to work fine but after number 4 adopted us it felt like there was a cat everywhere I looked. It didn't help that number 4 was a boy and bullied the girls mercilessly.
He went to live with the inlaws nc was spoiled rotten for the last years of his life
