Character: Ferret Idea Development

After more feedback today, I've been able to develop my story idea more for the Character project. I am debating about either making two ferret characters or a ferret and a guinea pig. While in the real world it'd make more sense if it was two ferrets, having two different animals will make the characters more unique from each other. I think it'd also add to the humour of the tubby messy male guinea pig thinking the ferret is a strange, feminine, sort of mythically beautiful guinea pig when in reality she's a different species.
