If you want to give Jocks a second chance try Hamlet, having a small and cute jock makes them more tolerable. And, rather adorable with his very un-jock like appearance.
I also am a long-time Rosie fan <3 It took me a while to find her anywhere, but that might have just been me. If you don't want another cat then I think Bunnie is another good choice. My favorite uchi is Pashmina, she's so pretty and underrated! Mira and Phoebe are really cool and also the most popular. If you like a sort of gothic look, you might love Muffy, and Fuchsia is pretty cool looking as well.
