Kangaroos and other macropods such as wallabies and wallaroos use their tail to balance while jumping.
A squirrel's tail twitches to communicate with other squirrels, show emotions like excitement or fear, and help with balance while climbing and jumping.
The kangaroo's tail plays a vital role in balancing the animal, both when it is bounding along, and when it is just walking slowly. Kangaroos cannot move their legs independently (except when swimming), so the tail plays a vital role in helping the kangaroo to balance as it moves.
The kangaroo uses its tail for balance as it hops.
A rat is an animal that does not fly. It also has a long, rounded, naked tail. The tail is used to counter balance the rat's movements, and is also very sensitive.
To some degree, this will depend upon the cat. Cats use their tails for balance while walking and jumping, so losing part or all of a tail may cause your cat to have trouble balancing while walking and jumping for a while. Over time, your cat will learn to compensate for the loss of his/her tail, but it probably won't have quite the same surefootedness that it had prior to the amputation.

Kangaroos are not able to sit due to the structure of their hind legs and tail. Instead, they use their tail for balance while standing or hopping.
The human body doesn't need a tail because we aren't animals. Almost every animal has a tail for extra balance. Our balance are our big toes. We only have a TAIL bone, which is an extra bone that used to be where our ancestors had tails for balance.

Not all animal's have tails and it also depends on the type of tail and the animal. Some use the tail for balance some for grabbing things, some for whipping away flying bugs that annoy them, some for all the reasons above.
