If you're looking for a very powerful and pleasant companion cat, then look no further than the American Shorthair. Selectively bred to maintain a muscular, stocky, and working body, the American Shorthair is available in a wide variety of colours and patterns, Dr. Burch said. She further explained that because they're easygoing, affectionate, family-oriented cats, they're great companions and playmates for families with children. "Along with their loving personalities, they are low-maintenance and healthy cats rarely needing medical care other than their annual checkups with your veterinarian," she said.
