This is the perfect size for cats, small dogs or birds. I have a feral partially blind feral mama cat who just had babies a couple of days prior. I set 2 large dog crates tie wrapped them together so she and her babies would have a place to live. I had food/water bowls on each side so when I was handling the babies; I'd slide a piece of plastic thru' so I could handle them, clean the babies, clean that crate, put in fresh food/water without her attempting to come after me. This size bowl perfect for her all day.
