My wife’s foster sister’s cat had a litter of kittens, two of which were missing part of a hind leg, and rather than let them go to a shelter (where we were sure they’d be euthanized) we took them. The male had a bit more of his leg than his sister and had a peculiar humping walk, so we named him Long John after the peg-legged pirate. His sister ended up being named Muffin, to keep with the bakery theme.
We also had an orange kitten who from the start was a ball of fluff, so he was named Pumpkin. He never grew out of his kitteny fluffiness, and had to be given a “lion-cut” periodically because his fur would get so matted.
