These metal bowls are better than the plastic if you cat has feline acne. You just need to make sure it's the right size for your pet. Make sure it's not too deep for cats and it has to be big enough for the daily food intake, but not too big to make them too fluffy! They're super easy to clean and can be put in the dishwasher too!

Pros: Will last forever!

Cons: Need the right size
