Now usually when pets have accidents that injure their back legs, they're attached to a wheelchair-type rolling device so that they can still move around. That's not the case with Oscar, who lost both hind paws to an accident back in October. A talented surgeon created metal peg legs and embedded them straight into the bone for this feline. Coated with a substance to help bone cells develop directly over them, now both bone and skin have grown over the connecting areas, allowing this kitty to move almost normally once again.
