New Member - Senior Cat with FIP & Diabetes

Turtle & Donut

Member Since 2026
Hi Everyone :)

I am seeking some comfort and advice for my cat - Donut, a 13 year old ginger since I rarely see cases like this online. My cat has been diagnosed as diabetic since 2024 and has been receiving regular insulin shots - 1 unit of insulin shots, twice a day. 3 months ago, he was diagnosed with FIP since he was losing weight, constantly sleeping and losing strength. Throughout his treatment, his weight remained the same - 3 kg. Based on my previous experience with another cat that was diagnosed with FIP and successfully recovered, their weight would usually go back to normal after a month. When he was brought back to the vet for a check-up after his FIP treatment was completed, the doctor advised to onboard him since the FIP was still not fully cured. They suspected the diabetes was in the way of the FIP medicine being absorbed by the body. Ever since then, it feels like he's gotten worse.

Currently receiving treatment for FIP relapse & Diabetes

He is not grooming himself and only eats wet food. He didn't eat today but he ate wet food yesterday and was on a feeding tube for the days prior - being fed blended up diabetic kibbles. His blood glucose reading today was 30 mmol/L. Yesterday it was 6 mmol/L. The doctors are trying out different insulin brands to see which is compatible with him and using 3 units for now.

His prime years - 2020. Before his diabetes diagnosis and FIP. This chonker was a whole 6 kg of pure joy.

Its's sad to see how much he has devolved. It hurts to see him the way he is now. I'm hoping he'll make a turn for the better and he's able to fully heal from the FIP and get into remission. Right now, I'm hoping he lives to see another day at least. He meowed at me yesterday and the day before when I went to see him - I'm taking that as a sign that he's still fighting. A part of me feels like he wants to just go home. But taking him home right now would risk him having a seizure and passing. If any of you has experienced this, I hope you are able to provide some advice because I'm not sure whether to take him home or keep him at the clinic for longer. Could the treatment be contributing to his decline, or is this progression from FIP?
 
Welcome to FDMB
He's such a beauty, I am sorry you are going thru this , I was reading about FIP, at least he's getting treated, You do not mention the insulin the Vet is giving, but in the meantime I will tag a member that has an extensive knowledge in cats' medical issues and illnesses and can answers your concerns 🤗

Update: his blood glucose reading today is 19 mmol/L. He is getting 2 units of Novomix. The vets are saying that this brand seems to be working for him as it's lowering his reading. He's still responsive and is on a feeding tube now.
 
Hi everyone,

His weight has dropped to 2.5 kgs from 3.4 from when he was onboarded. His blood glucose readings so far (mmol/L):

17/1
Morning - 16
Night - 24

18/1
Morning - 10.1
Night - 11.7

19/1
Morning - 23.7
Night - 18.5

20/1
Morning - 23
Night - 24.7

21/2
Morning - 28

Not sure why his numbers are going up. It could be the Somogyi effect. Right now, we're thinking of bringing him home since it feels like the numbers are worsening at the vet. It's a big risk and we're hoping to have some at home care advice. What should we prepare and what food should we provide. The vets do not recommend wet food and to put him entirely on diabetic kibbles. Problem is he doesn't enjoy eating diabetic kibbles and enjoys wet food more. They did mention that anything we give him might not be processed by the body.
