A little calf in America is walking again with the help of two prosthetic legs.

Hero lost his back legs due to frostbite after being abandoned in a frozen field.

Luckily he was found by Kitty Martin, who runs an animal rescue centre in Texas.

Kitty nursed him back to health before taking him to expert vets who carried out the incredible procedure.
