I love these bowls, my cat not so much but this is her problem)) She's been an indoor cat for almost 3 years and gained a lot of weight. This bowl makes her eat a lot slower than usual. So we went through the rebel period when the cat was mewing for a couple nights straight demanding to bring her old bowl back. But after we passed that and she got really hungry, she got used to eating from this one. And now we all are pleased.
