My cat Zinger was having stomach issues, and he even had to see the vet over the problem. His stomach condition has been fixed I believe because of this interactive feeder. Zinger would eat too fast and then vomit. This interactive feeder helped him to have to paw each morsels out onto the floor. This helped him digest slower, and keeps them active for quite some time. Zinger has not had any hair-balls etc since he started eating from this type of feeder. I would recommend this item to help pets eat slower, have less stomach issues, and have something to help them stay active.
I think I ordered this from Amazon. My vet advised me of this product, and I am glad he told me about it. The vet called it a pet food dispenser.
