The first pedigreed cat to claim the “made in America” label, the Maine coon has a long history of charming peopleBy Kim Campbell ThorntonAndrews McMeel SyndicationThey make them big in Maine. The Maine coon -- the state cat of Maine -- is not only one of the largest domestic cat breeds, but also one of the most popular in the United States. Nicknamed “gentle giant,” or sometimes “coonasaurus,” Maine coons can weigh as much as 25 pounds! It’s often said that Maine coons don’t mat excessively, but that’s only true if you comb or brush them out at least weekly. Maine coons’ large size also makes them prone to hip dysplasia, which you may have thought only affected dogs.
