Wow, bowls have come a long ways from the old days when I was using a margarine tub to feed the bunnies!
These new additions are, quite frankly, awesome. A stainless steel bowl that snaps into a metal holder that stays on bunny's home. It looks good, it works great, and cleanup...I just throw them in the dishwasher!
The bowl is approximately 5 across by 1.75" deep.
