Thread: Does the age of neutering/spaying affect size of Maine Coons?

We have a Newfoundland puppy, now 10 months old, and like most giant breeds Newfs are prone to hip dysplasia and other bone problems. So we are not neutering our Newfie boy because studies have shown he needs those hormones to make big strong bones.

We asked our Maine Coon breeder if it was the same for MCs and she said we could wait until our kitten boys are 10 months old or earlier when their urine starts getting strong to neuter them. Generally breeders say, "By 6 months." I'm hoping they don't get stinky or spray before 10 months because I want them to get everything they need to grow big and strong and have no developmental deficiencies.
