Hey there, I’m Jake, and I’ve been helping run our cat food supplier spot for almost 8 years now. Most days, I’m the guy who’s fielding calls from panicked cat parents at 7 PM, answering DMs at 10 PM from someone whose vet just said their fluffy tabby has diabetes, and testing 10 new recipes a week (don’t worry, I only taste the taster samples—no actual cat food for me, trust me). Cat Food
If you’ve landed here, odds are you’re staring down the same terror my friend Mia did last year when her 5-year-old siamese, Mochi, got the diagnosis: feline diabetes. Suddenly, every grocery store bag she’d grabbed for years was useless, every YouTube “expert” was spouting conflicting garbage, and she stayed up 3 nights straight scrolling until her eyes burned. I get it—when your cat’s health is on the line, the last thing you want is to sift through overhyped claims that sound too good to be true.
First, let’s hit the basics that every vet will probably yell at you for if you skip them, but I’m gonna keep it real: feline diabetes isn’t the same as human type 2, and it’s not a “you just need to cut treats” fix. Cats are obligate carnivores—meaning their bodies are built to survive almost entirely on meat, no grains, no carbs, barely any plant stuff. When a cat has diabetes, their pancreas either doesn’t make enough insulin or their body ignores it, and carbs are the #1 trigger for that blood sugar spike that wrecks everything. I’ve seen clients switch to a “healthy” low-calorie food with whole grains and watch their cat’s blood sugar swing like a pendulum at 3 AM. It’s brutal.
So what actually works for diabetic cats, and what do we at our company know from working with vets and testing real cats (our own included) that you won’t see on Instagram? Let’s break it down straight—no jargon, no fancy words.
First off: PROTEIN IS NON-NEGOTIABLE, AND NOT JUST ANY PROTEIN. We’re talking high-quality, animal-based protein—like chicken, turkey, salmon, or lamb, the stuff cats would hunt in the wild. Not “meat by-products” (that’s just leftover parts no one else wants, no nutritional value) and definitely not plant-based protein (like soy or pea protein—cats can’t digest that well, and it spikes blood sugar). For a diabetic cat, protein should make up AT LEAST 40% of their food, and even better if it’s closer to 50% on a dry matter basis. Wait, dry matter? Yeah, that’s the only number that matters—most food labels list “as fed,” which includes water, so a can that says 8% protein might actually be 40% when you strip out the water. I learned that the hard way when we tested a competitor’s “high-protein” can that flopped for a diabetic tester cat.
Next: CARBS. We’re talking less than 10% of dry matter, and honestly, for most diabetic cats, under 5% is way better. Carbs like grains, legumes, potatoes, even some fruits (yes, even the “healthy” blueberry treats) turn into sugar super fast in a cat’s body. I had a client whose vet said her cat could have “small amounts” of sweet potato—she tried it, and her cat’s insulin doses had to go up by 2 units a day. No thanks. Avoid everything with corn, wheat, rice, oats, peas, lentils, or any kind of added sugar (even “natural” ones like maple syrup). If you see a cat food with more than one carb listed in the first 5 ingredients, put it down. I don’t care if it’s labeled “diabetic formula”—check the ingredient list, not the marketing.
Fat is important, too, but not too much. Cats need fat for energy, but too much can lead to weight gain, which is a whole other stressor for diabetes. Aim for 15-30% dry matter fat, mostly from animal fat (like chicken fat, not vegetable oil). That stuff is easy for them to process, doesn’t mess with blood sugar, and keeps their coat nice and shiny. We make sure every batch we test hits that range—nothing too high, nothing too low.
Now, let’s talk about wet vs. dry food, because this is the question everyone asks. I’m gonna be blunt: wet food is almost always better for diabetic cats. Dry kibble is basically 40-50% carbs, even the “low-carb” ones—they need those carbs to make the kibble hold its shape. I’ve had more diabetic cat parents switch from dry to high-protein, low-carb wet food and watch their cat’s insulin needs drop by half within 8 weeks. The only time dry is okay is if your cat refuses wet (stubborn little furballs, I’ve got one named Tater who’d rather skip meals than eat wet), and even then, you have to get a super low-carb kibble—like less than 5% dry matter carbs. Don’t get suckered into the $50 “veterinary diabetic kibble” either—most of those have hidden carbs that don’t show up on the front label. We tested a popular vet brand kibble once, and it was 18% carbs on dry matter—way too high.
Wait, what about treats? Oh man, treats are the #1 hidden culprit. I’ve heard of cats going into blood sugar crisis because their owner gave them a single “diabetic treat” labeled low-calorie. 90% of cat treats have hidden carbs, even the freeze-dried ones if they have added fillers. For diabetic cats, treats should be a tiny piece of plain cooked chicken or a small piece of freeze-dried salmon with zero added ingredients. No exceptions. I know it’s hard—Mochi, the siamese I mentioned earlier, would rub against Mia’s leg for hours begging, but they stuck to the rule, and now her blood sugar is finally steady.
Now, let’s get real about our experience here—we don’t just make food and hope it works. We partner with 2 local vet clinics that specialize in feline diabetes, and we have a test group of 12 cats (including 4 with diabetes) that we tweak recipes on every month. Last year, when we rolled out our new line for diabetic cats, we had 10 tester cats go from needing twice-daily insulin to once-a-day, or even none at all (under vet supervision, obviously—never adjust insulin without your vet’s okay). That’s not a fluke—we tested 17 different recipes over 6 months, checking every batch’s carb count, protein level, and how it affected the tester cats’ blood sugar. We even adjusted the texture because some diabetic cats have dental issues and can’t handle big chunks—small, tender shreds work way better for them.
I know a lot of you are still scared that you’re doing something wrong, or that you’ll mess up your cat’s health. Let me tell you something: I’ve had so many clients DM us at 2 AM panicking because their cat’s blood sugar is high, and 9 times out of 10, it’s because they snuck in a treat with hidden carbs or grabbed the wrong bag from the store. The good news is that adjusting their food is one of the most impactful things you can do for a diabetic cat—way more than any little supplement you see online.
If you’re still confused about what to look for, let me sum up the rules I live by with diabetic cats: 1) 45-55% animal-based protein on dry matter, 2) Less than 8% carbs on dry matter, 3) Mostly wet food, or if you have to do kibble, find one with <5% carbs, 4) No hidden fillers in treats, 5) Always check with your vet before making any diet changes.
At our company, we don’t just sell cat food—we talk to cat parents every single day, we test our food on real cats, and we work with vets to make sure every recipe is actually helpful, not just marketed. If you’re a cat parent with a diabetic furbaby and you’re tired of guessing, reach out to us to chat. We can walk you through our test results, answer any stupid (no question is stupid, trust me) questions you have, and help you figure out what would work best for your cat. No sales pitch, no pressure—just us trying to help cats live their best, most steady blood sugar lives.
Wait, one last thing—don’t listen to random people on Facebook who say “my cat got off insulin just by switching to this cheap food.” That’s irresponsible, and every cat is different. Always work with your vet, always monitor their blood sugar, and always make sure any diet change is tailored to your specific cat. The food is a huge part, but it’s not everything.
If you’re ready to take the next step and talk about what we offer for diabetic cats, we’re here. No need to fill out a 10-page form or call during 9-5—we’re available most days via our general line, and we love chatting with cat parents, especially those going through the diabetes struggle.
