Do you have a cat who bolts down every meal? It seems that no sooner than you’ve fed him in the morning, he’s done and waiting for more. Maybe your cat vomits because he’s eaten so quickly, or maybe he doesn’t even chew and puts himself at risk of choking. Either way, with an empty dish, boredom can set in, and obesity can become a serious issue that threatens his health.
