Most cat food marketing is noise. High protein usually means slightly less corn than the bag beside it.
Nulo is one of the few brands where the number holds up. Average protein across the range sits around 44 percent, which is roughly ten points clear of typical supermarket kibble and comfortably above most premium brands too.
So the food is genuinely what it says. The question is whether your cat needs that much, and whether the price makes sense for you.
- Nulo cat food averages around 44 percent protein, roughly ten percentage points above typical supermarket kibble.
- Nulo has had no recalls since the brand launched in 2009.
- Nulo FreeStyle recipes include the patented GanedenBC30 probiotic, a spore-forming strain that survives the kibble manufacturing process.
- Nulo recipes list animal protein as the first three or four ingredients and are grain free across most of the range.
- High protein food is not automatically right for every cat, and cats with kidney disease need veterinary guidance before switching.

What does 44% protein actually change?
Cats are obligate carnivores, which is a precise term rather than a marketing one. They derive energy from protein and fat efficiently and handle carbohydrate poorly, because their metabolism evolved on a diet of small animals.
Typical budget kibble runs 30 to 34 percent protein with 40 percent or more carbohydrate, because grain and potato are cheap bulk. Nulo’s average of around 44 percent inverts that balance considerably.
In practice a higher protein food means a cat can hold muscle more easily while losing fat, which matters for the very large number of overweight indoor cats. It also means smaller portions deliver the same nutrition, which narrows the real cost gap a little. Not by enough to make Nulo cheap, but by enough to be worth mentioning.
The GanedenBC30 probiotic, explained
Nulo FreeStyle recipes include GanedenBC30, a patented probiotic strain. The reason it is named rather than described generically is worth understanding.
Most probiotics die during kibble manufacturing, which involves heat and pressure that live cultures do not survive. GanedenBC30 is a spore-forming strain (you can confirm any brand’s recall status in the FDA recall database), meaning it can go dormant and survive the process, then reactivate in the gut.
So the claim is more meaningful than the average probiotic sticker on a bag. Whether your individual cat notices is another matter, and probiotics are supportive rather than curative. A cat with persistent digestive trouble needs a diagnosis from a vet, not a supplement.
The 6 Nulo products, reviewed
Nulo Raw Medley Turkey, Chicken & Trout Adult Dry Cat Food, 10-lb bag: best overall
Raw Medley mixes high protein kibble with freeze-dried raw pieces, which is a neat way to get the palatability of raw without the handling or the freezer space. Turkey, chicken, and trout lead the recipe. If you want one Nulo bag to try, this is the most interesting one.
Nulo FreeStyle Turkey & Duck Recipe with Omega Fatty Acids High Protein & Grain-Free Dry Cat & Kitten Food, 14-lb bag: best grain-free dry
FreeStyle Turkey and Duck is the classic Nulo formula, with animal protein in the first three or four ingredients and the patented GanedenBC30 probiotic worked in. Grain free, low carbohydrate, and priced in the premium tier. This is the recipe most Nulo reviews are actually describing.
Nulo Digestive Health Chicken & Whitefish Adult Dry Cat Food, 10-lb bag: best for digestion
Chicken and whitefish with extra digestive support. Worth saying plainly: a cat with chronic loose stools or repeated vomiting needs a vet, not a different bag. But for a cat that is merely a bit sensitive, a probiotic-supported formula is a reasonable thing to try.
Nulo Prowess Healthy Weight Adult Dry Cat Food, 13-lb bag: best for weight control
Prowess Healthy Weight keeps protein high while cutting fat, which is the correct way to slim a cat down. Never crash-diet a cat: rapid weight loss can trigger hepatic lipidosis, a dangerous liver condition. Aim for slow loss with your vet checking progress.
Nulo Freestyle Chicken & Herring Canned Cat Food, 5.5-oz, 24 ct: best wet food
Chicken and herring in a shredded texture, sold by the case. Nulo’s wet range carries the same high protein philosophy as the kibble but adds the moisture that dry food cannot. Buying by the case brings the per-can cost down to something more reasonable.
Nulo FreeStyle Chicken in Broth Cat Food Topper, 2.8-oz, case of 24: best topper
Chicken in broth, designed to go over a complete diet rather than replace it. Useful for tempting a cat off a hunger strike or adding water to a kibble-based diet. Read the label as a topper rather than a meal, because that is what it is.
When high protein is the wrong call
This gets skipped in most Nulo reviews and it matters.
- Chronic kidney disease. Cats with diagnosed CKD are usually placed on controlled protein and phosphorus diets. Do not switch a CKD cat to a high protein food without your vet’s approval.
- Abrupt switches. Moving a cat straight from budget kibble to a rich, high protein food commonly causes diarrhea. Transition over seven to ten days.
- Certain liver conditions. Protein needs change, and that decision belongs to your veterinarian.
If your cat is older, drinking more than usual, or losing weight, that warrants blood work before a diet change rather than after it. The Cornell Feline Health Center covers feline kidney disease in detail, and this article is educational rather than veterinary advice.
Who should buy Nulo
Buy it if you have a healthy adult cat or a kitten, the budget stretches, and you want genuinely high protein rather than the marketing version. Overweight cats trying to keep muscle while losing fat are the clearest case.
Skip it if you feed several cats, if your cat has a condition needing a controlled diet, or if the price would make you resent the purchase. Compare with our best dry cat food picks and the best wet options. Adding a water fountain does more for a kibble-fed cat than upgrading the kibble does.
The bottom line on Nulo
Nulo delivers what it advertises. The protein figure is real, the probiotic choice is technically sound rather than decorative, and there has not been a recall in the brand’s entire history. On formulation it is among the better foods you can buy.
Price is the argument against, as it is with every food in this tier. If you want to try it, Nulo Raw Medley Turkey, Chicken & Trout Adult Dry Cat Food, 10-lb bag is the most interesting starting point because the freeze-dried pieces tell you quickly whether your cat is interested at all.
Frequently asked questions
Q: Is Nulo a good cat food?
Nulo is a high quality cat food. It averages around 44 percent protein, lists animal protein in the first three or four ingredients, includes a patented probiotic that survives manufacturing, and has never been recalled. Its main drawback is a premium price.
Q: Has Nulo cat food ever been recalled?
No. Nulo has had no recalls since the brand launched in 2009. You can verify the current status of any brand through the FDA pet food recall database.
Q: How much protein is in Nulo cat food?
Nulo cat food averages around 44 percent protein across the range, which is roughly ten percentage points higher than typical supermarket kibble and above most premium competitors.
Q: What is GanedenBC30 in Nulo cat food?
GanedenBC30 is a patented spore-forming probiotic strain included in Nulo FreeStyle recipes. Unlike most probiotics, the spore form survives the heat and pressure of kibble manufacturing and can reactivate in the digestive tract.
Q: Is Nulo good for cats with sensitive stomachs?
Nulo makes a Digestive Health recipe with added support for sensitive cats. If your cat has ongoing loose stools or vomits regularly, see a veterinarian first, because persistent digestive symptoms are usually a medical issue rather than a food preference.
Q: Is Nulo safe for cats with kidney disease?
Not without veterinary approval. Cats with chronic kidney disease are often prescribed controlled protein and phosphorus diets, and a high protein food may not be suitable. Discuss any diet change with your vet.
Q: Is Nulo better than Acana?
Nulo and Acana are both premium high protein foods with clean recall records. Acana leans on whole prey ingredients including organ and bone, while Nulo emphasises protein percentage and its probiotic. Either is a reasonable choice for a healthy cat.
