Editor’s Note: Even tough this article was first written in 2012, I periodically update the information to keep it current. I try to answer as many general questions in the comments as I can. I cannot always verify the veracity or accuracy of information or recommendations provided by readers in comments. If you would like me to evaluate a brand or product not mentioned on the list in this post, or if you would like individualized advice for your cat, please schedule a consultation.

If you’ve read this blog for any length of time, you know that I’m passionate about species-appropriate nutrition for cats. Cats are obligate carnivores, and they need meat not only to survive, but to thrive. The optimal diet for a cat is a properly formulated raw, home-cooked or grain-free canned diet.
Never feed dry food
Cats shouldn’t eat dry food; even the grain-free dry varieties are too high in carbohydrates.
Dry food is the equivalent of junk food for cats. It’s really not all that different from feeding sugared cereals to kids. Cats are obligate carnivores: this means they need meat not just to survive, but to thrive. They cannot get enough nutritional support from plant-based proteins such as grains and vegetables, because, unlike humans and dogs, they lack the specific enzyme that processes plant-based proteins metabolically. They need few or no carbohydrates in their diet. Feeding foods high in carbohydrates can lead to any number of degenerative diseases, including diabetes, kidney disease, and inflammatory bowel disease. Dry food is the leading cause of most urinary tract problems, and it is responsible for the obesity problem among cats. Dry food has also been implicated as one of the contributing factors to diabetes, which is reaching epidemic proportions. 1 in 50 cats may be affected, with overweight cats being at increased risk.
And contrary to the myth that just won’t die, dry food does not clean your cat’s teeth. Most cats don’t chew their kibble long enough for any of the scraping action that is the theory behind this myth to kick in. What little they do chew shatters into small pieces. Some pet food manufacturers offer a “dental diet” that is made up of larger than normal sized kibble to encourage chewing, but in my years at veterinary practices, I’ve seen many cats swallow even those larger size pieces whole. Additionally, dry food leaves a carbohydrate residue in the cat’s mouth that actually encourages growth of tartar and plaque.
Articles about feline nutrition, and one-on-one consultations
You can find many of the articles I’ve written about this topic in the Feline Nutrition section right here on this site. I also provide one-on-one consultations if you need help with transitioning your cat to a healthier diet.
What I look for in a food
- Protein is listed as the first ingredient on the label, and the meat/poultry used is fit for human consumption. If the meat is organic, that’s even better.
- The food is grain-free (no rice, barley, or any other grains. Even though these are considered healthy in human nutrition, cats’ digestive tracts are not designed to digest the unnecessary carbs).
- The food does not contain by-products, corn, soy, or any other fillers.
- Ideally, I’d like to see no carrageenan in the food. Some of the brands on the list below have carrageenan in some of their flavors, so check labels carefully.
- Ideally, I’d like a food to be GMO-free. Some of the brands on the list below may contain GMO’s.
Avoid fish-based foods
A word about fish: most cats love fish-based foods. I recommend using them sparingly or avoiding them altogether. The primary fish used in cat food are salmon, tilefish (usually identifed as ocean whitefish on the label) and tuna. Each of them presents health issues, because fish can contain toxic doses of common water pollutants, heavy metals, and other contaminants.
Sadly, much of the fish that goes into pet food is contaminated with heavy metals and other toxins. (On a side note, that is also true for fish sold for human consumption.) Mercury is considered one of the top ten chemicals of major public health concern by the World Health Organization.
Fish used in pet food manufacturing often contains whole fish, guts and bones, which can increase phosphorus levels of the food. This can be a problem for cats with kidney disease.
Some cats are sensitive to fish-based diets and develop urinary tract problems that resolve when fish is removed from their diet. Additionally, fish based foods may contain menadione, a synthetic form of vitamin K, which has been banned by the FDA for use in human supplements.
I am often asked what brands I recommend. Unfortunately, there are many diets on the market that sound good based on what the pretty packaging says, but when you take a closer look at the label, you realize that there’s not much substance behind the marketing claims. The brands listed below are foods that I either currently feed to Allegra and Ruby, or have fed to them in the past.
This list is not meant to be exclusive, and it does not mean that there aren’t other really good diets out there. It just means that these brands are the ones I’m comfortable with after doing thorough research.
I recommend the following foods (listed in no particular order). If you would like me to evaluate a brand not on this list, I would be happy to do so – please contact me for fees for this service.)
Best Wet Cat Foods
Addiction I only recommend the carrageenan free formulas. They are a bit higher in carbs than I like to see, but I still consider it a good brand.
Best Raw Cat Foods
Dehydrated raw diets
Gently cooked diets
