Which one might be better

which sex might be better to keep with mum as i have already posted about millie and her babies we are deff gonna be keeping one of them we have two boys and one girl and my heart wants to keep the black with tigger stripes down his chest and front but i just wondered if millie would preferably get on better with another female in the house or better with a male what do you all think x

In my experience, a resident female will generally accept a neutered male a lot quicker then another female.

I've had several females (spayed and not) that wanted to rule the roost and really did not like another female joining the group - they accepted almost every male tho.

The only way I had two females get along was a female that was kept from the mother (with the rexes).

With our barn cats, the top female (spayed) ran off or killed by chasing them to the road - every female in the group. She tolerated the males staying (neutered). That is why Ling was never allowed outside after the brothers/sisters left - because LoCal would have killed her.

I have heard that the opposite sex is easier to introduce to an adult cat. But, I have also heard that if the kitten is spayed/neutered the sex doesn't matter. I also would wonder if it matters to a mother cat who will be letting her own kitten grow up with her. Maybe one of the breeders will know the answer to this!
