For one guinea pigs and rabbits cannot reproduce! Lol. Secondly it’s a common myth that it’s ok to keep guinea pigs and rabbits in a hutch together as the rabbits are dominant and will bully the guinea’s making their poor little souls very miserable Google it and you’ll find a lot of articles backing that up.
As far as names, [name]Ginger[/name] is nice if one is ginger! Maybe you should wait to say how they look first! I have two gorgeous 3 year old boy guinea’s, [name]Jack[/name] (black) and [name]Harvey[/name] (ginger and white). Good luck but please I beg you to study more about those darling little animals before you get any because no offence but you don’t seem to know much about them and it’s not fair on them! Anyway hope you find some lovely names
