If my two cats were still around, they would be a Purrloin and a Purugly.
The first one would be a Purrloin because of her once being a feral kitten, contributing to a very skittish and street-like personality, and the fact that she was a black cat.
The second one was very old and grey, and because of that she started getting a bit chubby. She also wasn't very afraid of much.
