Beware! The rabbit I had years ago got sick one time and was dehydrated. He wasn't really drinking much, so the vet said to give him watered down gatorade. We did, but he never went back from that. He absolutely refused to drink water. So beware. Unless you need to give your rabbit something besides water to hydrate him, it's probably best to stick with just water otherwise you might end up having to go to the grocery store for him all the time.
