As with other heavily built breeds, it’s important to keep Maine Coon cats from becoming overweight, something that can easily happen if the cat is free-fed (food kept in the bowl at all times) rather than fed measured meals twice a day. For all cats, staying lean is healthier. For Maine Coons, which are prone to hip dysplasia, staying lean can prevent the development or worsening of joint issues. For advice about what to feed or how much to feed daily, talk to your veterinarian or breeder.
