I like Zoey, she doesn't look very Buttercupish to me either.
All our cats have 1 name but we have tons of variations off those names, same with the dog, we rarely call her by her actual name.
Cat names Anony Mouse, we call her Mouse, Mouser, Mouser Kitty or Fat Cat. lol Sometimes we call Mouser Garfield because she's built like he was drawn.
We have Tinkerbell, we call her Tink, Tinker, Tinky Winky, Stinky Tinky. LOL
Tigger, we call him Tig, Tig-Tig, Tigger-Wigger, Tiggy-Wiggy, Tiggy-Wiggy-Woo-Woo and Tigger-Licious. LOL
Autumn (the dog), we call her Autumn only when she's in trouble, otherwise she's our weeto doggie, wee, wee-wee. She's a mini doxie so she's tiny, so we called her little doggy, which in baby talk became weeto doggy. LOL
