I have the Lexit water bottles and I have 2 three month old rabbits that just can't seem to get the hang of them. There are three buns together in the same cage and the third drinks from it just fine. The other 2 wait for it to drink then rush over and lick it's chin trying to get a drink. When that bun leaves they stay there licking the metal tube and the cage wire trying to find any water that they can. I have a small crock in with them that I have to fill several times a day just so I can be sure they are drinking. I tried taking the crock out over night several times and they are pretty thirsty by morning. Any suggestions would be greatly appreciated.
