Input: I love the concept and design of these bowls. When they first arrived my cat was very curious about them, but a month later she has hardly touched them. They are heavy duty, however, that is where their good points end. The bowls don't retain heat nearly as well as ceramic bowls do. On several occasions when we were away from home for longer periods of time our pet would throw food or water down onto her bed because it felt colder than room temperature.
Output:
Bad review
