The Maine Coon is America's only 'natural' breed of domestic feline. It is four times larger than the Singapura ( the world's smallest breed of cat). I owned a Maine Coone and he was huge, 18 lbs. his name was Bob. He lived until he was 15. He was one of the best cats I have ever owned. Maine Coones are very clever and they love water. Bob could always be found on the bathtub edge playing with the water while I bathed. Gosh I miss him.
