What type of food should I be feeding my cat?
It's a common question heard by veterinarians: should I give my cat wet or dry food? This article explores some of the reasons for giving each type of cat food.
Wet (canned) food is beneficial for cats because it provides moisture. Cats in the wild get most of their water from the prey they consume, with little or no need for drinking it on the side. In fact, cats have evolved with a very low thirst drive as compared with other species.
For convenience, hard food beats wet food paws down, which is why most people with cats include hard food in their cats' diets. For instance, when you leave the house for a while, it makes sense to leave out hard food, not wet food, which will spoil and become unappetizing (and messy to clean).
