Thread: True about neuter/spay a MC cat...

Hi ale.agos, if it were me I would get both cats neutered sooner rather than later. I have had three maincoons, two of which were neutered at 12 weeks old, one male and one female and both these cats were enormous. My other boy Oscar was neutered later (6.5 months) and he is the smallest of the three. It is becoming more common in the UK for breeders to neuter kittens before moving to their new homes as this prevents irresponsible breeding. In your case it is really important that your cats don't mate due to then being siblings. As musicalife has said, Baloo and Bluebelle don't know they shouldn't mate and while Bluebelle may not be sexually mature for some time yet, do you really want to take the chance? Yes maine coons are slower to mature, but there are individual differences and she could well be able to become pregnant at only 5.5 months.
As for males spraying, I believe that once they start this behaviour, it can be really difficult to stop. The choice is yours but I would rather have two healthy happy cats than risk pregnancy. And as I have said, my experience suggests that neutering early does nothing to limit growth; if anything, it can make them bigger as they spend longer in the juvenile state where rapid bone growth occurs.
