A dog named Pay de Limon (Lemon Pay) runs fitted with two front prosthetic legs at Milagros Caninos rescue shelter in Mexico City August 29, 2012. Members of a drug gang in the Mexican state of Zacatecas chopped off Limon's paws to practise cutting fingers off kidnapped people, according to Milagros Caninos founder Patricia Ruiz. Fresnillo residents found Limon in a dumpster bleeding and legless. After administering first aid procedures, they managed to take him to Milagros Caninos, an association that rehabilitates dogs that have suffered extreme abuse. The prosthetic limbs were made at OrthoPets in Denver, U.S., after the shelter was able to raise over $6,000. REUTERS/Tomas Bravo (MEXICO - Tags: SOCIETY ANIMALS)

Tzvika, an injured female turtle, walks with the aid of her newly attached wheels at the Wildlife Hospital in the Ramat Gan Safari near Tel Aviv January 5, 2011. About two months ago, Tzvika was run over by a lawn mower and suffered severe damage to her shell, and a spinal injury that affected her ability to use her rear limbs. The wheels, attached by veterinarians at the safari, elevate the turtle to keep the shell from being worn down and enable her to walk.

Hofesh, an injured male green sea turtle, swims in a pool after an artificial fin was attached to his back at the Israel Sea Turtle Rescue Center, in Michmoret north of Tel Aviv April 9, 2014. The turtle was brought to the centre some four years ago missing both limbs on the left-hand-side of his body, but on Wednesday the artificial fin, designed by an industrial design student, Shlomi Gez, was attached to Hofesh's back, offering him stability and a more permanent solution to his disability. Hofesh will not be released back into the wild as he cannot survive if something were to happen to the fin. REUTERS/Baz Ratner (ISRAEL - Tags: ANIMALS SOCIETY ENVIRONMENT)
