A squirrel named Karamel has become the world's first squirrel to get a prosthetic limb. Karamel lost his front paws when he got caught in a trap. But a group of scientists in an Istanbul University decided to lend him a hand. Orthopedists at the university built Karamel a set of prosthetic wheels to replace the missing front paws. And he appears to be literally speeding down the road to recovery.
