they are quadrupeds.
there are 2 major categories of quadropeds.
homologous motion is like a frog or rabbit or kangaroo where
the two front feet move then the two back feet.
then lynx is probably the other kind, where the front feet and back feet move separately. there are two versions of this which i don't remember
In walking, and for many animals running, the motion of legs on either side of the body alternates, i.e. is out of phase. Other animals, such as a horse when galloping, or an inchworm, alternate between their front and back legs. An alternative to a gait which alternates between legs is hopping or saltation, where all legs move together. As a main means of locomotion, this is usually found in bipeds or semi-bipeds. Among the mammals saltation is commonly used among macropods (kangaroos and their relatives), jerboas, springhares, kangaroo rats, hopping mice, and gerbils. Certain tendons in kangaroo hind legs are very elastic, allowing kangaroos to effectively bounce along conserving energy from hop to hop, making hopping a very energy efficient way to move around in their nutrient poor environment. Saltation is also used by many small birds. Frogs and fleas also hop.
it also says cats are digitrade, whatever that means.
