Diet as a cure

Hello Everyone! We just joined the forum and I am curious about something. Ed was diagnosed last Thursday (I accidently stated two weeks ago in another thread, time has been lost on me since the diagnosis). We absolutely believe his diabetes is food related.

Some background: I've done a lot of research on cat diets over the decades because I believe like humans, a good diet is super important to their health. I've always had all of our cats on a high-protein, low/no carb wet food diet. Then November 14th, 2025 happened. We lost our sweet ginger boy to a brain tumor. After he died, Gabby, one of our girls, was diagnosed with crystal issues. Against my better judgement and feeling terrible after the loss of Julius, I decided to allow the cats to free-feed prescription dry food hoping this would work better in Gabby's favor as she needs to be able to eat more throughout the day to stay hydrated and that S/O food does a great job in getting them to drink. The vet said it would be good for the other cats as well so free-eating it was. My biggest mistake - listening to the vet regarding their diet. I knew better but let my guard down anyway because I was so sad about losing Julius, it was nice to be able to just 'be lazy'. I miss him terribly. Depression from his loss got the better of my judgement.

We started dry prescription Royal Canin Urinary S/O then switched to the Gastro with S/O index on our vets recommendation. Everyone was eating a normal non-excessive amount, all was seemingly going well. About 6 weeks in, we started to notice the changes in Ed. Subtle at first - he stopped playing, lost weight and his coat got rough looking. Then the excessive drinking started. We took him to the vet last week when he started hopping in the bathtub to get water while we showered. That's when he got his diabetes diagnosis.

He was started on insulin and he was doing better. My husband and I absolutely suspected the food was responsible for the diabetes. I won't get into what I've found regarding Royal Canin prescription S/O diets and diabetes, I'll just say that this is most likely a case of correlation equaling causation. After his diagnosis, I immediately weened the cats back to the all protein wet food diet, feeding twice daily while kicking myself for ever allowing them to eat dry food loaded with carbs in the first place.

This past Tuesday, Ed crashed, the hypoglycemia hit him hard. We had just received his blood glucose meter that evening so we quickly learned how to use it and started taking readings. His first reading during the crash was 45, then 15 mins later it was 42! We did the honey on the gums twice, got excellent advice from members of this forum and went from there until he was stable. We called the vet the next morning and was told to skip his next insulin dose, do more readings, etc. I suspect that he was in reversal and the insulin he got before dinner the prior evening, before we were able to test his blood glucose, wasn't necessary which is what led to the crash.

We stopped the insulin as directed by the vet and he hasn't had any yesterday or today thus skipping four doses. We've been doing fasting testing before he eats and he went from a 183 on the 12th to 110 prior to dinner tonight, 3/13. We are so happy to see this normal blood-glucose reading. He's been doing great except the blow-out super stinky poos he's having while his digestive system recovers. I do have him on probiotics for that. He's eating like normal, drinking normal and he has gained weight, a few ounces at a time. It seems as though we've reversed his diabetes.

I've done some research and found that this is absolutely possible and can even happen this quickly. Has anyone else experienced this? If so, do you mind sharing your experience? I want to make sure we're not missing anything. Thank you for your time, I really appreciate it! Everyone I've chatted with has been so incredibly helpful and amazing. This is a great site, that's for sure!
 
Diabetes can't be cured, just well managed to the point where remission is possible A brief course of insulin may be needed for some cats as well. Some cats can go into remission with just a simple change to a low carb canned food only diet (raw and home cooked are also options).

Many dry foods are super high in carbs and is the cause of diabetes for many cats. This web site goes into more detail about dry food and diabetes and other topics: Feeding Your Cat: Know the Basics of Feline Nutrition – Common Sense. Healthy Cats. Prescription foods are pretty terrible. They have no magic ingredient that helps a medical condition. Royal Canin S/O dry is 30% carbs, way too much for a cat. Many vets have little education on proper nutrition and some get commission for selling prescription foods.

Thank you for the info! That's the main thing I was curious about, can it be cured or is it in remission? We're not throwing out the insulin or skipping his blood glucose readings, that's for certain. I've read that cats, especially if diagnosed when they're older, are more likely to go into remission if treated quickly with a change in diet, it looks like that's what is happening with Ed. We are to speak with the vet next week with an update but I'm also wondering if there are any signs to look out for in case he relapses? I hope we can keep him in remission for a long time! I read that one cat went over 9 years. That's pretty amazing!
 
some cats go on remission after a while on insulin, some with a change of low carb foods, some take years, some, like my Corky, will be a life time diabetic, but I am happy to know he's pancreas keep healing, and he is tightly regulated all cats are different, but it cannot be cured, Corky was diagnosed 4 years ago he was 10, he will be 14 in October

Wow this is great news my so glad Ed is okay & doing good & no insulin :bighug: that is the best news!!!

I do believe that Ed could have just needed the diet change & no insulin to begin with all together. I don't get on the board often. When I got on the other night & saw your post "please help" I was only getting on to put numbers on my boys spreadsheet because it wouldn't let me do it on Google docs. I saw your post & that know one had responded to you so I replied back to you hoping you would get my reply because it had been 45mins since you posted.

I'm sorry for the loss of your Julius & for Gabby & the other kitty's & you having to go through the prescription food nightmare. I've been there trusted my vet for the first year & a half, fed Panzer the prescription diabetic food loaded with carbs, gave him 6units of insulin 2xs a day no testing, I was clueless. If I had not found this site I do believe my boy wouldn't be here right now. I've read a lot on here & read about other members cats doing things that Panzer was doing before finding this site & he was hypoing & I had no clue. The only thing that saved him was I hate to say it was the high carb food.

I've been testing & feeding & giving him the proper dose since October of 2021. He was diagnosed in January of 2020 thanks to the FDMB & so many members I have gained the knowledge to take proper care of him & I will keep trying to reach remission.

I really hope that Ed is now diet controlled :bighug: you guys are such good cat parents. Please keep us posted & feel free to tag me anytime!!!

Corky can still go into remission in fact if I'm not mistaken he earned a reduction on 2-27 he's been in normal numbers since then. I believe it's 7 days 14 cycles in normal numbers is a reduction, he was 119 that day & hasn't went above that since. I know you like him in those lower greens though & @Suzanne & Darcy would know best.
