My cats hate cold food. They will actually refuse to eat it, so when I found out about Animals Instinct pet food warmer I was delighted. This low-watt oven stores 12 5.5 oz cans or pouches of cat food that come out just the right temperature for my cats' enjoyment. They go nuts for their food now! The warming enhances the flavours, but doesn't alter the composition at all, like a microwave does. This is definitely one of those products that I didn't know I always needed. As a bonus, vets can use them to warm fluids and warm packs! -TC
