Of course, you'd be pretty awkward. But you'd pick up speed if your legs changed accordingly. If you began walking on all fours, you might be as swift as an antelope. This type of foot model is termed unguligrade. Cats, dogs, and many other animals with paws do not walk on the very tips of their toes and are called digitigrade.

Hippopotamus stomachs are divided into three chambers. In addition, these animals ruminate. Ruminants generally eat quickly, swallow their meal into a large stomach chamber called the rumen.
