Give your rabbit fresh water daily. It's important to change your rabbit's water every day to prevent bacteria from growing. Use a water bowl made of ceramic, rabbit safe plastic, or metal, as these are easier to clean. 

You Can also affix sipper bottles because they cannot be easily tipped over in the cage, however, rabbits get dehydrated easily with a sipper bottle. The sipper bottles can also collect germs at the spout. Choose a water container that works best for you and your pet and they can enjoy fresh water 24/7
