Maine Coon Cat FAQ
“How big do they get?”
At full-growth (3-5 years of age) a female typically weighs between 10-14 pounds and males tend to be in the 13-20 pound range, without being fat or overweight.
“Do they need much grooming?”
Maine Coons do not need much grooming and a weekly combing is all that is usually required to keep the coat in top condition.
“But I thought Maine Coons had extra toes…?”
Some "original" Maine Coons were polydactyls (had extra toes). However, modern purebred Maine Coons are rarely polydactyls. This is because all cat associations automatically disqualify polydactyls from competition in the purebred classes. Because of this, most polydactyls were culled from the Maine Coon breed decades ago, and only a few breeders continue to work with them. Since the polydactyl gene is dominant, you can't get a polydactyl kitten unless at least one of the parents is also a polydactyl.
“Is that a Maine Coon? I thought all Maine Coons were brown.”
Maine Coons come in a wide variety of color combinations. The only colors you won't find are the Siamese-type colors.
“I think my cat is part Maine Coon. How can I tell?”
The Maine Coon is America's native longhair cat; it evolved naturally in response to the New England climate. Your cat's ancestors might be similar to the cats that founded the Maine Coon breed. However, it's impossible to tell from just looking at your cat if it is related to the Maine Coon or to any other breed. Because the Maine Coon is a natural breed and hasn't been bred to extremes, there are cats all over the world that resemble the Maine Coon. The only way to tell for sure if your cat is a Maine Coon is to look at the pedigree.
