My two cats are Chilli and Mae. Mum named Mae because she liked that name, and Chilli's breeder named him Chilli Pepper as a kitten, I really liked it so I just kept it as Chilli.
Our dogs are Tessie and Mister Fox. Tessie was going to be renamed, but she had already had 3 names by the time we got her, so we decided to keep her name. Mister Fox was a nickname, because he looks a bit like a fox. We stuck with the name Mister Fox, but call him Foxie. His old owners called him Ralph, there's no way we could keep that name... My sister also just got a dog named Meeka, but I don't know why she chose that name...
Our guinea pigs are Gus, Bernie and Cheezel. Gus, because it just suits him, Bernie, because somehow, at the time, he reminded us of Bernie Fraiser, and Cheezel because he's a blonde colour, like a cheezel.
George the sheep got his name after my grandfather, I think. And I named our other sheep Clover because I thought it was a pretty named that suited her well.
The rabbits are Henry and Aleu. They belong to my sisters. Henry got his name because he was a boy, and it suited him, and Aleu got her name because my sister heard the name on a cartoon (I think) and liked it.
I think that's everyone!
