6-year-old cat with slightly elevated GGT

[Mobypuppy]

My 6-year-old male cat, Puppy, did a pre-op blood work before dental today, and came back with a slightly elevated GGT (5 U/L, normal between 0 - 4). Ultrasound also showed that the gallbladder wall is slightly thick but everything else (except GGT) in the blood work is within the normal range.

Vet suspected it might be a diet issue. She mentioned that sometimes a high protein diet might be the cause. For context, I've been feeding Puppy a full wet food diet called Zealandia. The protein rotates between brush tail, venison and wallaby. This is the first time I've heard of a high-protein diet giving problems to the gallbladder.

For the time being, Puppy is given a 2-week course of Ursopet Oral Suspension, and is scheduled for another round of blood test and ultrasound in 2 weeks time to see if the medication works.

Does anyone have a similar experience to share? And what I should look out for.
Thanks so much!

I searched this site (you probably did too) and found nothing that was specifying any case with GGT being the only elevated element. I also have never heard of it being protein related. The only things I found are these two articles, which you probably found yourself, but just in case you didn't.

Regardless of whether or not protein can impact the gallbladder, your vet's course of action seems to be a reasonable one - obviously starting with the second round of blood tests.

Most definitely will follow-up with the vet in two weeks time. Thanks!
