While dry cat food is cheaper and more convenient (can be stored easily and makes litter boxes easier to clean), wet (canned) food is generally believed to better meet the nutritional needs of a pet cat because it is closer to raw food and provides better hydration. The smell of canned cat food can be quite off-putting; however, it is better for the cat's health. While some experts recommend eliminating dry food from a cat's diet, it is often more practical for pet owners to maintain a balance of both dry and wet food in their cat's diet.

Dry cat food can contain a lot of filler, including more carbohydrates than a cat would eat in the wild.[1] For example, Friskies Indoor Delights dry food is 30% protein, 9% fat, 5% fiber, 42% carbohydrates and 12% moisture.

Wet cat food is mostly made up of meat or fish, which is closer to a cat’s natural diet.[2] Friskies Classic Pate wet cat food is 10% protein, 5% fat, 8.63% carbohydrates, 1% fiber, 78% moisture, 3.5% ash and 0.05% taurine.


Dry food averages about 10% water. As a cat’s natural prey is about 70% water, cats fed dry food usually don’t get enough water. This can lead to chronic dehydration and health problems like Chronic Renal Failure and urinary crystals.[3]


Wet or canned cat food is generally more expensive than dry food. For example, while 6.3 lbs of Friskies Indoor Delight dry food is $7.18 from Walmart and typically lasts a month, 12 5.5 oz meals of Friskies pate canned cat food costs $5.48 from the same store.


Dry cat food can be left constantly in the cat’s bowl, so that the cat can eat whenever it is hungry. It does not spoil when opened.

Wet cat food is messier and smellier, and it has a shorter shelf life once it has been opened. It cannot be left in the bowl for more than a couple of hours.

Health Issues

Cats that eat only dry food are slightly more likely to become obese that cats that eat wet food, due to the high carbohydrate levels. Cats that eat only dry food are also slightly more likely to develop diabetes.[4]

Wet cat food might lead to dental problems including gingivitis.[5]
