same reason we walk or run on two legs that's the way they were made
Cheetahs can climb but not well as they do not have retractable claws and their legs are designed more for sprinting than climbing.
~50cm i love CHEETAHS! WOOHOO!
They have four of them.
The way they are different are lions and tigers can not run as fast or that they do not have spots or legs as long as the cheetahs.
The answer is a bed. A bed has four legs, it sits on the floor with its legs, and "waits" for someone's legs to come and lie down on it.
4 legs
mice have 4 legs :) look on google at pictures of them :p
How it looks, works, and is made. For example on Living things, a Animal like a cheetahs back spine is longer than ours and bones are thinner and build so it walks on four legs, we are build on two legs with our back spine up.
on all four feet
Because they have slim, powerful bodies and long legs for their size.
