ProSelect Stainless Steel Coop Cups - Durable 64oz Pet Water & Food Bowls for Cages, Chicken Coops, Rabbit Hutches - Rustproof Animal Feeder for Birds, Rodents, Small Pets

I noticed most people get these for dog crates, but I have similar ones for my ferret nation. The problem with other one is the bowl's metal edges crack on top and the 'ring' has rusted on the back where it attaches to the cage. I was really thrilled at the quality of these bowls. They are more substantial metal and easier to pull out of the ring. So far so good with the rust issue, because of the coating on the ring and mount I don't expect rusting.I work with animals and those that are looking to add to a crate, the 8 oz. size of these are good for a small breed dog, puppy, kitten, and cat as well. Definitely a very good value, shipped fast and arrived in perfect condition.
