Sonic is a four-month-old black kitten who was born with a deformity in his front leg that makes it difficult for him to walk. He's actually missing a bone; instead of two bones in his foreleg, he only has one, so it can't bear his weight like it should. Luckily for him, he was taken in by the Denver Animal Shelter, whose staff has been working with students from the Art Institute of Colorado to help him walk normally. So far the kitten has tested out five different 3D printed prosthetics, and while the final model can't be made until he reaches his full size, he has been responding well to the prototypes so far. Sonic is only the first animal taken on by the two institutions; they hope that through their partnership, they can help many other injured and deformed animals through 3D printing.
