ELI5: How are animals like felines able to jump and leap insane distances? What makes humans unable to do the same?

The design of the hind legs has a lot to do with it.  


Animals like cats and deer walk on their rear toes.  The "heel" is quite high off of the ground.  So their rear legs have three major segments instead of two, giving them more power and range of motion.  This leads to bigger jumps.  


And you also have to be able to land safely.  Humans have to land on the same legs that they jumped with.  Four legged animals jump with their rear legs, and land with their front.  The front legs and their joints have evolved to be great shock absorbers.  For example, the shoulder joint of a deer has an incredible range of motion, because there's no direct connection from the leg bone to the bones of the torso.  It's all just connected by soft tissue.
