My childhood cat was a calico named mama-san, because my mom had watched karate kid before adopting her and she had kittens beforehand.
We adopted a cat in 2016 that I named little sister, after the dog in Mulan with a similar name.
A few months later we adopted a cat that I named Yoki, after the name yoko, as I was a fan of the Beatles and the rosemary wells book.
We got a third cat named baby, we didn't have control over her name but we also call her little lady.
My aunt has a big fat cat named Humphrey, he's a silly grouch of a longhaired cat.
