Grain Free Cat Food, Does It Matter?

Have you heard about grain-free cat food? A few years ago, the word “natural” got attached to both people and cat food products, even though there was no legal definition of the term or specific benefit—folks just like the idea of a “natural” product. Today the latest buzz-word is “grain-free” and a wide variety of grain-free cat foods are now available.

I’ve updated this post to include Karma, and some more recent research. I’m lucky that neither Seren-kitty or Karma-Kat have ever been a picky eater or had any food allergies or sensitivities. Seren lived to (almost) 22 years and thrived on commercial dry cat foods. Some of my colleagues, who I greatly respect, might be shocked at that—but for me, if it ain’t broke, no reason to fix it.

Seren maintained her healthy 6-pound svelte figure and c’attitude with no sick days whatsoever (until a sneezy attack when I switched to a new cat litter, I have to give credit to good care, good food, and good kitty genes. Karma-Kat gets a mix of commercial dry and canned foods, along with healthy treats from the table now and then.


What does grain-free mean? And does it matter to your cat, or is it just another marketing term designed to sell cat food? Are there grain free wet cat foods or only dry?

I got to tell you that both the “natural” and the “grain-free” terms have more to do with marketing than meeting the cat’s nutritional requirements—of course, that’s my opinion, only, and your mileage may vary. It’s not that foods labeled “grain-free” are bad—not at all, and in fact for a specific population of cats, they may be the best cat food.

I’m just saying that cat foods that contain grains are not inherently evil. And I’m also applauding pet food companies that don’t just jump on the bandwagon but do respond to the human “cat parent” concerns with new food options to address those concerns–and also use that opportunity to EDUCATE about the issues involved. Bravo!

So let’s examine the question. What’s the objection to feeding grain to cats? Well, most cats don’t graze out with the cows, or guzzle down gallons of grain. Given their choice, cats munch small furry critters–and if you’re Karma-Kat, the occasional cricket.

Savvy cat folks understand that felines are obligate carnivores, which means they are animal eaters and do best on diets with high quality animal proteins. (Hey, I’m preaching to the kitty choir here, but in case there are lurkers, let’s cover the basics, shall we?)

Here’s the deal, though. Cats CAN digest carbs (especially when properly processed in commercial diets). They may gobble up the teeny grain-filled tummies of their prey. No, it’s not the main meal, but it is an important part of the total nutrition picture.


Carbohydrates provide energy and are obtained from starches and grains. And many folks forget that grains also contain proteins. Your cat’s body doesn’t care if that amino acid comes from mouse or corn, so proteins provided from meat and grain combos properly designed can be terrific kitty fuel. That’s why kitties for years have survived and even thrived eating well-designed commercial dry cat foods that include ingredients like corn, wheat, or rice.

The operative words there, of course, are well-designed. Poorly designed, out of balanced nutrients can hurt the cat, whether the ingredients are paw-some or awful.

Even good diets may pose problems if the balance gets out of wack, or your cat’s needs are unique. When Kitty eats too much and exercises too little, the resulting Tubby Tabby may become predispose to other health issues like diabetes–and special formulations may be necessary for these cats. There also are cats sensitive to specific kinds of ingredients in cat foods that develop allergic reactions to protein sources (like corn or fish). For cats with skin issues or upset tummies the vet says are food allergies or sensitivities, a grain-free diet may be the purr-fect option.


It doesn’t matter if the food says “grain-free” or “natural” on the label (hey, poison mushrooms are natural, too! Just saying…). What matters is the correct balance of the various nutrients in the food, and the higher the quality of those ingredients, the more easily your cat’s body can utilize the nutrients.

Maybe you simply believe grain-free cat food is healthier and prefer foods without grain. Good for you! Depending on the formulation, it could be a great choice for your cat. However, if you’re choosing a grain-free food to avoid carbs, think again—the carbs may still be in the food but in another form. Potato starch might be even higher in calories than a grain ingredient. Hey, that doesn’t mean it’s bad but do your research to be sure you’re getting what you think. Some of the unusual ingredients in pet foods might surprise you–and how much they benefit the cat, even though Kitty might not be “naturally” inclined to nosh beet pulp. Heck, I don’t think Seren would ever have snagged her own salmon, either!


Every cat is an individual. Isn’t that why we love them? A one-size-fits-all diet no longer is necessary and you can find the right formula that fits your feline. Talk to your veterinarian about what’s the most appropriate food for your heart-kitty. Age, health status, and more goes into match-making foods to individual cats.

Bottom line, “natural” and/or grain-free cat food isn’t necessary for good cat nutrition—with very few exceptions having to do with ingredient sensitivities. Although the majority of cats don’t need a grain free food, they can do very well on properly balanced formulations when that’s your preference. Heck, because cats are such individual, your cat may do better, who knows?

Woof Wednesday: Food, Glorious Food & Worry-icity!


“Num, num, num, num…”


Yes, it’s happened again and the culprit is salmonella. But it’s not home cooking folks or raw feeders, but commercial foods once again. BRAVO to Diamond Foods, the manufacturer/packager of a number of brands, that kicked off a VOLUNTARY RECALL as a precaution even though only small amounts of product actually was suspected to be a problem. Since that initial announcement, additional foods–dog, puppy, cat, kitten–and brands have been added to the recall list. Brands include:

  • Chicken Soup for the Pet Lover’s Soul
  • Country Value
  • Diamond
  • Diamond Naturals
  • Premium Edge
  • Professional
  • 4Health
  • Taste of the Wild
  • Apex Foods
  • Solid Gold

You can find links to the various products along with batch codes and dates to ensure your pets’ foods are still safe or should be returned in this recall blog.


How do you know a pet food is the best for your furry wonder? Every pet is different, of course, but there are ways to figure things out. Reading labels gets you part of the way there–but the labels are a legal document and serve to satisfy the regulators more than they do to inform the public. There are terms that have legal definitions but can be misinterpreted by pet owners (ain’t that the way legalese works?), and even some ways the labels can mislead (accidentally on purpose, LOL!) to get you to open up your wallet. After all, dogs don’t have thumbs or bank accounts so it’s up to us to choose wisely.

Here are a few links to further information about pet foods–much of this applies to cats, too:
