Ragamuffins come in at number two on our list as they can grow to be up to twenty pounds. They are a very muscular cat with a broad chest and can take up to five years to fully mature. You wouldn’t realize how muscular they are due to their long coat which is surprisingly easy to groom. They come in a wide variety of accepted colors and patterns so long as the coat texture and length is acceptable. Ragamuffins are very friendly and personable cats, but they are also known for their docile nature. They have a tendency to be a bit vocal when they are trying to get your attention or tell you something. Despite their long coat and because of their gentle nature, they are not suited for outdoor life.
