Obviously my cats did fine on dried food but this is what one vet has to say. It’s an article on feeding an older cat but it seems like the attitude toward wet vs. dry food may be changing.
Over the years, most veterinarians, including me, recommended dry cat chows for all their feline clients. Vets noticed that cats on dry kibble tended to have cleaner teeth, less gum disease and less of a problem with obesity. Dry cat kibble also lacks can-liner chemicals that some veterinarians associate with hyperthyroidism (bisphenol-A). (ref)
We are less sure if that is reason enough to recommend dry diets now.
Dry cat kibble is very convenient for owners. It doesn’t smell like canned food does and it doesn’t spoil nearly as quickly as canned foods do once they are opened. It is economical and, theoretically, meets all of your pet’s nutritional needs. However, it is quite an unnatural diet for cats. Most dry cat foods are much higher in grain carbohydrates (and some in plant-based proteins) then cats were designed to eat. Some veterinarians associate the high carbohydrate content of many dry chows with susceptibility to diabetes. This has not been proven. Many dry cat foods have been sprayed with fats to make them more palatable. This fat can become rancid and unhealthy.
But the biggest potential problem is that cats eating dry diets almost never drink sufficient water to equal the hydration they would get consuming a canned or homemade diet. Some veterinarians associate this potential dehydration with kidney disease, and bladder disease (struvite/oxalate crystals). This is, again, unproven. Dry cat foods are also more susceptible to bacterial contamination (salmonella, etc.) than canned foods.

What to feed your animals is one of those things everyone has an opinion on and the opinions all seem to be different, even amoung vets so it’s kind of hard to figure out what the “best” thing to feed your animals is.
I never thought about it much with my cats. My childhood cat ate a diet of canned and dry grocery store food and wasn’t sick a day in her life and lived to be 20. My Bugsy developed urinary problems at 4, over 20 years ago when there weren’t so many foods on the market, and the Science Diet SD and CD were recommended to me by the emergency room vet and my regular vet. Those took care of the problem so I stuck with it. I stuck with the dry food because it was convenient and because they were kind of picky about it. They wouldn’t eat a whole can between them at one sitting and once it had refrigerated the left overs,even if I warmed it up they wouldn’t eat it. They lived good, long lives.
Now I have a dog and have looked into what is the best food for her and the dog world is like religion, there denominations all believe different things about food and training, various gospels and true believer who will preach their particular gospel at the drop of the hat, gurus, all of that, and many of these dog “religions” are completely contradictory to on another, like other religions. They can’t all be true but which one is the true one? You’ve got me.
A quality premium cat food, maybe a grain-free food like @SpatzieLover recommend might be a good choice be cats are strictly carnivores.
In the end, it is probably best to take your question to your vet and ask your vet about dry vs. canned food.
