A cat that had its back feet severed by a combine harvester has been given two prosthetic limbs in a pioneering operation by a UK vet.
The new feet are custom-made implants that "peg" the ankle to the foot. They are bioengineered to mimic the way deer antler bone grows through the skin.
"We have managed to get the bone and skin to grow into the implant and we have developed an 'exoprosthesis' that allows this implant to work as a see-saw on the bottom of an animal's limbs to give him effectively normal gait."
This has huge implications for people.
