Let’s see yours for your cat(s)
Kattepus, because I had a Norwegian neighbour who called our cat that when I was growing up and now it’s a nickname for any cat that lives with me
Pointy Boy and Noisy Boy, because he is both of those things
Little Shadow and Baggy (as in Bagheera) because he’s a black cat and has a habit of sleeping on things that he is camouflaged against
