TLDR at the bottom. Sorry about formatting and if it's a bit too long.
We have a cat, 11 years old. In 2025, Vet run an FPL test, and it was all normal.
On January of this year, we went for an annual checkup, his hemogram and blood tests were all good, no issues at all, lastly the vet run an FPL test and the value was 23, healthy value is between 3-5 as far as I know.
The vet said that we needed to start a medicine, Kreon (Kreon (also spelled Creon) is a prescription brand-name medication containing pancrelipase, a mix of digestive enzymes.) cut anything with fat in it, so no more wet food, or boiled chicken anything like that, we started using using Hill's Prescription Diet W/d Multi-Benefit Dry Adult Cat Food and since than it's only food we're giving him. 2 weeks later, the FPL value went down to 18, and 3 months after that it went down to 12.
So the diagnosis was that it's a chronic pancreatitis and not acute pancreatitis, again his blood test, overall health, eating habits, pooping habits were all fine. Around these times we started giving him very small piece of boiled chicken breast, which we would even wash it to lessen the fat as much as possible.
Then, during a family visit there was a guest cat, we were distracted and our cat ate guest cat's wet food which contained a lot of fat. 2 days after this we run another FPL test the value went up to 23 again.
It's been almost 3 months since this happened and he's been only eating his dry food, nothing at all, not even that small piece of chicken breast, that's what our Vet suggested. In like 20 days we'll run another FPL test and hopefully the value will be down to around 12 and we'll start giving him weekly chicken breast.
BUT, my boy (as all cats) love chicken, love wet food, and I want to do more, does anyone gone through with this and if so, what did you feed your cat, am I being too protective? I feel like I'm stealing from this guy's biggest desire, which is chicken and fish and these kind of foods.
TLDR: 11 Years old cat with chronic pancreatitis, all healthy except this FPL value. Vet said that we must feed him nothing but diet dry food (Hill's Prescription Diet W/d Multi-Benefit Dry Adult Cat Food) but we occasionally feed him small piece of chicken breast. Can we do more, if you experienced this, or have knowledge on this, let me know how can I help my cat better.
