How I Reversed My Cat’s Diabetes (Luke’s Story)

When my cat Luke was diagnosed with diabetes, I felt completely overwhelmed.

I remember sitting there, hearing the words “insulin injections” and “lifelong condition,” and thinking… how is this happening?

He was my baby. The thought of him being sick—and possibly needing shots every day—broke my heart.

But what hit me even harder was the guilt. I couldn’t stop thinking… did I cause this? Did I feed him the wrong things? Could I have prevented it somehow?

I felt like I had failed him.

I’m going to walk you through exactly what I changed, what worked, and what I wish I knew sooner — because my cat is now doing much better and is in remission.

The Symptoms I Almost Missed

Looking back, there were signs that something wasn’t right—I just didn’t fully connect the dots at first.

Luke was drinking a lot more water than usual. I was constantly refilling his bowl, and it just didn’t seem normal.

Then there was the urination. He was going much more frequently, and it became hard to ignore.

At the time, I didn’t realize these were classic signs of feline diabetes.

But once he was diagnosed, everything suddenly made sense.

The good news is that after making changes to his diet and starting treatment, those symptoms improved significantly. His water intake went back to normal, and the excessive urination became much less of an issue.

What Feline Diabetes Means

Feline diabetes is a condition where a cat’s body can’t properly regulate blood sugar. Many cats are diagnosed later in life, and diet plays a huge role in managing the condition.

At first, I didn’t understand how much food choices could impact Luke’s health—but that ended up being one of the biggest turning points.

The Biggest Mistake I Made

At first, I truly thought I was doing everything right—but looking back, I made some mistakes that likely made things harder for Luke.

I had been feeding Luke a dry food that was marketed as “high protein,” so I assumed it was a healthy choice. It sounded good, it looked good, and honestly—I trusted it.

But what I didn’t realize at the time was that many dry cat foods, even the ones labeled high protein, are still loaded with carbohydrates.

Carbs and cats? I had never even thought about that.

When I started digging deeper, I quickly learned that high carbohydrate intake can make it much harder to regulate blood sugar in diabetic cats. That was a huge wake-up call.

What made it even more frustrating was that even my vet initially said the food I was using was fine—and of course recommended a more expensive brand they carried in-office.

That’s when I realized I needed to start asking more questions, doing my own research, and really understanding what I was feeding my cat.

What I Changed That Actually Helped

Once I realized that diet might be a huge part of the problem, I decided to make some changes right away.

The first thing I did was eliminate dry food. I switched Luke to a wet food-only diet, focusing on options that were higher in protein and much lower in carbohydrates.

I also started adding simple, cooked chicken breast—nothing added, no seasoning, just plain chicken. It gave him an extra boost of protein and something fresh that I felt good about feeding him.

Treats were another big change. I got rid of the dry treats completely and replaced them with freeze-dried chicken treats. They’re simple, high in protein, and don’t come with all the unnecessary fillers and carbs.

Around this time, Luke was also started on insulin. Our vet placed a glucose monitor , the FreeStyle Libre, on him for about a week so we could track his levels more closely. There is an app that you can download and monitor when in range which is nice. Of course I was checking it every minute like a lunatic!

That’s when things really started to shift.

Watching his numbers begin to come down—and eventually return to a normal range—was such a relief. It felt like everything we were doing was finally working. I stopped his insulin basically on day 2 after I realized the change in his diet had already taken effect. Inside the monitor app, you can write notes, and I documented everything I did and why. The info was sent to my vet and they were able to see what I saw and I was called from my vet himself and was told I did the right thing in stopping his insulin because he has stabilized. After a few more days, I received another call from my vet telling me Luke was in remission!!!! I literally cried I was so happy!

Within days of changing his diet, I started seeing improvements — and within a short time, my cat went into remission!

I’ll be doing a full breakdown of the glucose monitor we used and how the app works in another post.

What I Feed My Cat Now (After Diabetes)

After a lot of trial, research, and paying close attention to what worked for Luke, I found a routine that I feel really good about.

Right now, I feed him Weruva B.F.F. OMG (Best Feline Friend Oh My Gravy!) packets, specifically flavors like Chicken & Turkey “Text Me” and Chicken “Charge Me Up.” These are high in protein, low in carbohydrates, and something he genuinely enjoys eating.

I stick with the packet versions because they’re convenient, portion-controlled, and easy to serve.

In addition to his regular meals, I also give freeze-dried chicken treats from Lilsnoots. They’re simple, high-protein, and free from unnecessary fillers—plus, both Luke and Reyna absolutely love them.

Speaking of Reyna, she’s also been eating this way and is thriving on the same diet.

Seeing both of them do so well has made me feel even more confident that I’m finally feeding them in a way that truly supports their health.

This was one of the biggest changes I made—and the one that made the biggest difference.

This is the exact food I switched to : Weruva B.F.F. OMG (Best Feline Friend Oh My Gravy!) packets, specifically flavors like Chicken & Turkey “Text Me” and Chicken “Charge Me Up.

and Lilsnoots freeze-dried chicken treats.

What I Wish I Knew Sooner

Looking back, there are a few things I really wish I had understood sooner.

First, I had no idea how much carbohydrates matter for cats. I always thought of carbs as something humans needed to watch—but I never realized how much they could impact a cat’s health, especially when it comes to blood sugar.

I also wish I had trusted my instincts more. When the vet initially recommended starting insulin right away, something in me felt like I should try changing his diet first. Looking back, I wish I had explored that option more before jumping straight into treatment.

And if I’m being honest, I ignored the early signs for a few days, thinking they might just pass. The increased thirst, the frequent urination—I didn’t realize how important those symptoms were at the time.

But the good news is, once I started paying attention and made changes, things improved.

If there’s one thing I’ve learned, it’s this: trust your gut, pay attention to the small changes, and never underestimate how much diet can impact your cat’s health.

If you’re trying to figure out what to feed a diabetic cat, this is what worked best for me:

Chicken & Turkey “Text Me” and Chicken “Charge Me Up.

Lilsnoots freeze-dried chicken treats.
