Review on Wangstar Slow Feeding Pet Bowl - Bloat Stop Puzzle Bowl For Both Dogs And Cats - Anti-Skid Design With Fun Maze Feeder (Grey, 8''X1.9'') by Julian Locklear

I was having issues with my cats gulping down their food too quickly and without chewing, resulting in almost immediate regurgitation. I chose these bowls in particular because I liked the colors and the grooves in the bowl looked pretty deep, plus the price seemed fair. I've been using these bowls for a few weeks and they work perfectly! My cats have not thrown up once since feeding from these bowls, and they had no issues figuring out how to get to the food. They, on the other hand, are quite displeased as they can't stuff their faces anymore!
