Wet vs dry cat food: which is better for your cat?
Cats evolved to get most of their water from food, and a bowl of kibble is mostly not water. Here is what vets say about wet vs dry cat food, what each costs you, and when mixing makes sense.

FYI Summary
Here’s what matters
The short answer: both can work. Water is the difference.
- Both wet and dry cat food can be complete and balanced, so the label matters more than the format.
- Canned food is at least 75% water, while dry food contains only 6% to 10%, according to the Cornell Feline Health Center.
- Wet food helps cats take in more water, which is one reason many veterinarians recommend it over dry food, according to the Merck Veterinary Manual.
- Dry food is relatively inexpensive and canned food is generally the most expensive type, according to Cornell.
- Many cats do well on a mix of wet and dry food, and your vet can help if your cat has a urinary, kidney or weight problem.
Your cat's ancestors didn't do water bowls. They got most of their water from their prey.
Fast forward to your kitchen: a scoop of kibble, a water bowl your cat walks past twice a day, and a vague feeling you should be buying the cans. The cans cost more. Are they worth it?
Short version: both can be complete nutrition, and wet food's big advantage is water. Here is what the vet sources say, what each format costs, and how to choose for your cat.
Is wet or dry food better for cats?
Neither is better for every cat: both can be complete and balanced, and Cornell says the choice can come down to what your cat prefers. The Merck Veterinary Manual adds that wet food helps cats get enough water, which is one reason many veterinarians recommend it over dry.
| Factor | Wet (canned) food | Dry food |
|---|---|---|
| Water content | At least 75% | 6% to 10% |
| Cost | Generally the most expensive type | Relatively inexpensive |
| Taste | Highly palatable for most cats | May be less palatable than moist food |
| Water intake | Helps your cat get enough water (Merck) | Your cat must drink more from the bowl |
Why does water matter so much for cats?
Cats that drink less water are at higher risk of lower urinary tract disease, according to the Cornell Feline Health Center.
Cornell lists cats that "drink less water" among those at higher risk, along with middle-aged, overweight cats that get little exercise and indoor cats. Wet food is one way to get more water in; Merck also suggests several fresh water bowls and a water fountain, since many cats like moving water.
A blockage is also one of the bills pet insurance exists for; our cat insurance comparison works through a $3,000 example.
Can I mix wet and dry cat food?
Yes. Cornell notes that some cats like canned food, some like dry and some like a combination.
A common pattern is a wet meal or two plus a measured amount of dry. Keep an eye on the total: Merck warns that free-choice feeding can lead to overeating and obesity. Ask your vet how many calories your cat needs a day and split them across both foods.
How do I know a cat food is complete?
Look for the AAFCO statement on the label saying the food is "complete and balanced" for your cat's life stage; Cornell recommends checking it before choosing a format.
- Life stage: kitten, adult, or all life stages.
- Complete and balanced: the food can be fed on its own, not just as a treat or topper.
- Format second: once the label checks out, wet vs dry is about water, budget and taste.
Which should you choose for your cat?
Choose on three things: how much your cat drinks, your budget and what your cat will reliably eat.
Wet food probably makes more sense when…
- Your cat rarely drinks from the bowl.
- Your vet has raised a urinary or kidney concern.
- Your cat is picky and eats canned food more reliably.
Dry food may make more sense when…
- Budget is tight and the food is complete and balanced.
- You need food that can sit out for a while, with portions measured.
- You mix in wet meals for water and use dry for the rest.

Frequently Asked Questions
Is dry food bad for cats?
No. A complete and balanced dry food can be a healthy diet; the main trade-off is that it contains only 6% to 10% water, so your cat needs to drink more.
Do vets recommend wet food for cats?
Many do. The Merck Veterinary Manual says wet food helps cats get enough water, which is one reason many veterinarians recommend it over dry.
How much water should my cat drink?
It depends on the diet: cats on wet food get much of their water from food. If your cat suddenly drinks and pees a lot more, Merck says to talk to your vet.
Bottom line
Start with the label, then decide on water, budget and taste. Wet food adds water, dry food saves money, and many cats do well on both. Call your vet if your cat's drinking or peeing changes, and right away if your cat strains and produces no urine.
