physical characteristics
The anatomy of dogs varies tremendously from breed to breed, more than in any other animal species, wild or domesticated. And yet there are basic physical characteristics that are identical among all dogs, from the tiny Chihuahua to the giant Irish Wolfhound.

Cats typically weigh between 2.5 and 7 kg (5.5–16 lb); however, some breeds, such as the Maine Coon can exceed 11.3 kg (25 pounds). Some have been known to reach up to 23 kg (50 lb), due to overfeeding. This is very unhealthy for the cat, and should be prevented through diet and exercise (playing), especially for cats living exclusively indoors.
