Well, Thanks for all the info. I have pretty much decided that I will be only getting one of something that is not a hamster....either a gerbil or a guinea pig. Now just have to check into them.
Does anyone know, with a gerbil, is it better to get one of the solid plastic "habitrail type" cages or one that is more open on the top...a true cage? I thought that a solid one would get hot and icky with no air circulation for the poor thing, but then read somewhere that they don't like a draft and this type of cage is best???
