The Best Cat Food for Indoor Cats

When I got my cat, Cody, a few months ago, I was overwhelmed by the cat food choices at the pet store. All the brands have their marketing ploys designed to make you think theirs is the best or the healthiest for your cat. I know better than to believe marketing copy, but searching out a truly healthful cat food has been a daunting process.  There is a lot of information on the internet, some of it excellent, some of it marketing-in-disguise, some of it just well-intentioned misinformation. So I have spent the last few months sifting through all this information, reading labels, and trying different types and brands of food all in the hope of coming up with a healthy eating regimen for Cody. I hope my research can help you too!

The bottom line on this debate, from what I’ve found, is that canned food wins – umm, paws down. It comes the closest to mimicking the composition of prey, like mice and birds, which cats have evolved to eat. Feeding your cat a diet that is wildly different from the wild will likely result in poor health conditions like urinary tract infections, kidney problems, obesity, and diabetes.

So even though canned food is more expensive than dry food, in the long run – especially in terms of veterinary bills – feeding your indoor cats canned food will probably save you money.

Why is Canned Food Better?
In a word, it’s the nutrients. Or more specifically, the balance of the nutrients. Canned food gets it right; dry food gets it terribly wrong. Let’s take a closer look.

  • Water Content. Water is one of the most important nutrients for cats, but those on a dry food diet rarely get enough of it. That’s why they tend to have problems with their urinary tracts and kidneys, which in turn lead to litter box problems. Cats have what Dr. Lisa Pierson of calls a “low thirst drive.” She says that cats are designed to consume water with their food, not drink it separately. Canned food contains on average about 75% water, or roughly the same amount found in prey. Dry food contains only about 10% water at best so unless that cat regularly gulps from his water dish (which is highly unlikely), he’s probably not getting enough water.
  • Protein. Cats are carnivores. That means they need to eat protein from meat sources in order to get all the amino acids they need. About 50% of their diet should come from meat protein. Dry food tends to contain a lot of protein from plant sources, but this is not adequate for cats. The quality of the protein in most canned foods is generally much better.
  • Carbohydrates. Indoor cats do not need to eat many carbohydrates. If the energy from a carbohydrate is not used, the body converts it to fat. Cats, unlike dogs, typically don’t go for walks or runs to burn off carbs. It doesn’t take an animal behaviorist to know that cats spend most of their time sleeping! Since most dry cat food is full of filler carbohydrates, like corn, rice, and wheat, cats who eat this as a steady diet are at risk for becoming obese and/or developing diabetes.  In fact, Dr.  Elizabeth Hodgkins, has an 80% cure rate of diabetic cats by switching them to a low-carbohydrate diet. If your cat has diabetes, please visit her web site for detailed information.

Is Any Dry Food Okay?
So after all that, you may be wondering if you should feed your cat any dry food at all. This is where practical considerations come into play. In my own case, there are times when I need to be gone overnight, so I feed him small amounts of high quality, high protein dry food. It just doesn’t seem like a good idea to ditch him overnight with food he’s not familiar with. So I use the dry food more as a snack and try to incorporate a little playtime after he eats it so he can burn off some of those carbs.

Dr. Pierson provides another option: simply freeze portions of your cat’s food that can be set out once daily by your cat sitter. This is a good option, depending on how reliable your cat sitter is. It’s dangerous for cats to go without food so I will still leave dry food available to him if I’m gone.

Water, Water, Water

You must make sure fresh water is available at all times for your cats. I bought Cody a Drinkwell water fountain from Drs. Foster and Smith. Cats tend to drink more water when it’s moving, and indeed, Cody’s water consumption level has increased. I often see him drinking from the spout of the fountain for a few minutes at a time. I never saw him spend this much time at his water dish. The stainless steel version of this fountain costs $99, but there are others on the market in the $40 range. Since water is so key to urinary and kidney health – which in turn is key to litter box use – I think this is a good investment.

What about a raw food diet?
A raw food diet can give your cat exactly the diet he has evolved to eat, and this method of feeding is gaining in popularity. There are raw foods available on the market, Feline’s Pride is highly recommended, or you can make it yourself. For more information on this type of diet, as well as recipes and how-to’s, please see

Recommended Foods
As with most things, when it comes to cat food and formulas, it’s best to remember the mantra, “everything in moderation.” Feed your pet a variety of foods and formulas, leaning toward more poultry and duck versus fish formulas.

    Thanks for this information. I have an indoor cat- and he’s not a huge cat. I had him to the vet a few years ago and spent lots of money because I thought he had urinary tract issues. I have seen him use the litter box and all of a sudden his urine will shoot out of him and obviously go everywhere but inside the box. It’s like he is bearing down to ‘poop’ and then he pees! they told me there was nothing wrong with him. I think it’s from feeding him dry food all the time and your info makes me realize it. I am worried about incorporating the change in his diet – if you can offer any help I’d be grateful. I feel him IAMs indoor cat food – dry. Thank you.

      Dear Gina,

      Thank you for writing. I’m sorry to hear your cat is having difficulties. Since I’m not a veterinarian, I’m not qualified to give medical advice, but from what you write, I would say another trip to the vet is in order and as soon as possible. It could be your cat has an infection, for example, or other condition that would need immediate medical attention.

      You may want to do some quick research and see if you can find a different veterinarian. You can check the American Animal Hospital Association’s website for an accredited animal hospital in your area. If you’re interested in holistic medicine, you can search for a holistic vet on the American Holistic Veterinary Medical Association’s website. You could also try a general review site like (free) or (membership required) to see what people are saying about vets in your area.

      For more information on urinary tract diseases, check out what Dr. Pierson of has to say. And please have your cat evaluated as soon as possible!

      Now, according to Dr. Pierson, it’s best to transition a cat to a different food when the cat is healthy, to help minimize stress and to make the transition as positive an experience as possible. You don’t want to create a situation where your cat associates eating with stress, so it’s important to be mindful of your cat’s health and not try to make an aggressive change if he’s not feeling well. In the meantime, since a lot of urinary tract issues are the result of not getting enough water, the first thing to do—regardless of food—is try to increase your cat’s water intake. You can do this by offering him flavored water, like weakly mixed beef or chicken broth served at room temperature or slightly warmer (Dr. Pierson describes it as “mouse-body temperature.) You could also mix the water from a can of tuna in with his regular water.

      Another option is to invest in a drinking fountain, if you don’t have one already. I’ve since switched from the Drinkwell® Fountain to Pioneer Pet’s™ stainless steel Raindrop fountain because it’s about a thousand times easier to clean. You can find it on Amazon for about $35.

      Some cats will take to wet food without any problem whatsoever. If your cat falls into this category, hurray! Then you can, over the course of a few weeks, make the switch by gradually replacing his dry food diet with the wet food.

      The best thing would be to let him try some and see how he reacts. I would pick up a few different flavors and brands, ranging from the cheaper grocery store brands to the premium ones. The idea is to get him to start eating wet food. My cat is a very fussy eater, so in my case, I had to try several flavors and brands before I found the ones that he’ll reliably eat. Weruva tends to have a high water content, so this may be a good start for your cat.

      If he stubbornly refuses to eat wet food, don’t give up! There are things you can try. has a lot of excellent tips on getting a stubborn cat to make the switch from dry food to wet. One of my favorites is that you can try playing with your cat before he eats by tossing pieces of his dry food. This will stimulate his appetite and he may eat the wet food. (I particularly like this tactic because it’s a way to increase interaction with our cats, and it gives them a little exercise.) You could also try petting your cat when he’s at his food dish. I often have to stay in the room with my cat at least until he starts eating, and petting him does help him get started. Another option is to offer some wet with the dry, so he can gradually get used to the new food. You could also sprinkle crushed Temptations cat treats over the wet food. It’s made with animal digest—the very same stuff manufacturers put on dry food to make it so tasty to cats.

      I hope this information is helpful to you and your cat! Given his trouble, I’m impressed that he is using his litterbox.

      Best of luck to you and your cat! Feel free to write back and let me know how it goes.
