Meet Mercury, a kitten from Oklahoma who proves that cats don't need four legs to pounce and play.

The two-legged tabby was 4 days old and weighed just 5 ounces when he was discovered in a yard in September. He hadn't even opened his eyes yet.

He was missing his two front legs and all but one of his toes on his back legs.

His injuries are thought to be the result of a run-in with a weed whacker because neighbors had recently been doing yard work in the tall grass he was found in.

Mercury the kittenA local family took the tiny tabby to the vet where his wounds were treated, and then they brought him home.

They named him Mercury, bottle-fed him around the clock and cleaned his injuries multiple times a day. Despite his disabilities, he quickly grew into an otherwise healthy and playful kitten.

"Mercury does everything other cats do — he plays with toys, he jumps, plays with other cats and dogs, sleeps on the bed, uses a litter box, and believes he is the king of the world and should be worshiped," his owners write on his Facebook page.

Mercury learned to get around by walking on his hind legs, a move that's earned him comparisons to Tyrannosaurus rex.

His veterinarian says his unusual method of walking hasn't caused any damage to his hips or spine, but as he grows Mercury will require frequent check-ups to ensure his good progress continues.

There's currently no prosthetic or wheelchair solution for the kitten.

Prosthetics require that animals have at least 40 percent of the limb intact and working joints. Front wheelchair chairs for animals aren't common, and so far all the companies Mercury's family has contacted aren't sure the feline would accept one.

Mercury cat lying downWheelchairs haven't been completely ruled out just yet, but Mercury can't be assessed for such a device until he's fully grown.

For now, Mercury's family works with him on different aspects of movement, such as pushing himself up with his back legs, walking on different surfaces and jumping. At Christmas, he received a set of stairs, which he learned to climb so he can join his family on the couch and bed.

"We still encourage Mercury to move his body in his way and try to get him to do as much as he can on his own — carrying him around and doing things for him does not help him be a strong independent cat."
