I have a degu (small rodent) and had to buy him a new water bottle as the old one cracked.....I bought a newer style that you do not have to remove from the cage to fill, making it last longer, however, because of the way it is held onto the cage, it can't be put where his old one was. It is actually all the way at the other end of the cage, on the bottom level. He has seen it, and smelled it, as it is right beside his wheel (not beside his food where it has always been), but he does not seem to understand that he drinks from it. I have tried leading him over to it and tapping the end so the water comes out thinking he might understand that. I have not seen him drinking yet, and I know from experience that because he is so small he can't go too long without food or drink. How do I get him to understand what it is? I am starting to get worried that he might dehydrate......
