Cat paw got caught
If your cats are like ours and LOVE food, the product might not last long. After only 1 day, our feeders were full of scratches and teeth marks from the cats trying to get to the food. I worry that it is easier for bacteria to hide in these broken surfaces. Also, one cat ran to the feeder so fast while it was turning, that she got her paw stuck in the old compartment. It didn't seem to hurt her, but the feeder just kept trying to rotate, instead of stopping when feeling an obstacle.
