We had two Maine Coons, Regis and Maggie. They were the best cats EVER! They were so smart and gentle. You must brush their coats and it helps to get them groomed every once in awhile. Be prepared for hairballs.
That being said, I wouldn't hesitate to get another Maine Coon. They had the best personalities and they will really bond with you, like a dog does. They died within five months of each other and I was so depressed, I couldn't commit to another pet for nearly five years. We have a shelter kitty now and as sweet as she is, I miss the traits of the Maine Coons.
