uh!! so steve was attacked by a shark while saving his sister! and he lost a paw! here's my research Cats with missing paws normally move slower than a cat with all four, and their gait is less of a walk and more of a hobble. They will slip more easily on slippery floors, and cannot jump as high/far/well as they used to be able to. Cats with missing paws will be in extreme pain at the very beginning, but will not feel much pain after a little bit. A cat who is missing a paw/leg will need about a moon to recover and get back to "normal" although it will never have the same range of motion as it used to. A cat may feel a "phantom limb" sensation and try to, say, scratch an ear with their missing paw. Cats with missing limbs are more likely to develop arthritis early, because of the extra strain on their other paws. They also are at risk of obesity-related problems, so must be kept fit. A cat with a missing front paw might have a harder time bending down or sitting down. Stellar will feel extremely put down at first, but with the help of his sister the medic, his dada the medic, and his boyfriend the medic (all of different clans) helping him out, he'll slowly adjust to life on three paws instead of four.
