I only chose the name for Blueberry, guess its because he's a blue point, and I wanted a name to do with his colour.My other four are my grandmother's, but I go to her house often, so I'm always with them anyways. I really don't know how she got the names, I'll ask her sometime. I'll take a guess, I think the Silver is Sylvester because he's silver. That's pretty obvious. The dilute calico, Calley I think it's because dilute calico , so Calley. The solid white is Artemis, I don't know how, and the Blue&white is Lincoln, I don't know why either.
BTW, they're all Persians, with Blueberry- a blue point himmy. He's the only one that lives with me. But the other ones sometimes visits me too, but I usually go there. My grandmother also has these nicknames for them, I don't know how she got them
