My cat is a lovely little gem. But he can't quiet grasp how to make the food come down like he needs it to. So today I helped.
I put a plastic bowl with a lid on top of the food. Inside there are large rocks and glass gems for weight. When it's time for the food to come down to the feeder, the bowl helps by weighing it down and making him a happy boy! N-JOY!
