Well I hadn't planned on giving them hamster food either but that is what I ended up with instead of Guinea Pig
food, so I thought I might as well use some of it until I can get the right kind. I give them a little of the pellets and chunky stuff out of it. They seem to go for it right away when I put it in so that probably means it is not good for them
Both of mine are females as well. I have had them for almost a week and I thought with one drinking so much water I probably had better get the tank cleaned and was expecting a mess under the chips but there was none. It was dry. That really surprised me. No smell either.
