Why does my cat only lick the gravy and not eat the rest of the food?

Cats are known for being picky eaters and may prefer the taste or texture of the gravy over the rest of the food. It's also possible that your cat is simply being selective and enjoying the gravy as a treat. If your cat is consistently only licking the gravy and not eating the rest of the food, you may want to try offering different types of food to see if there is a preference for a certain flavor or texture.
