"This is my cat’s favorite food. He’s been treated expensive foods, pâtés, gravies, shreds… and he normally prefers pâté, but this is still his absolute all-time favorite."

— Diana

"The holes for water flow are very small and do not work properly, leading to stagnant water and temperature issues. The divider is not worth the money as it requires modifications and does not function as intended."

Bottom Line
