Cat with High ALT levels, Need Help/Advice

Sex: Neutered Male
Breed: Oriental Short Hair
Age: 17 months
Indoor kitty with leashed trips in backyard only.
No plants in house


Last month my kitty had his blood work results.  It showed a High ALT of 330 and "Increased" White Blood Cell Count. Everything else was normal.

Vet retested his blood work today and the results were higher, ALT of 445 and still Increased White blood Cell account.  Everything else was normal.

Vet also did a GGT test, should have the results back in a day or two.

Only other issue my poor guy has going on is having a fractured femoral head (will have surgery Wednesday for that).  High ALT level problems were going on BEFORE the leg fracture.
 
Not sure what is going on with his liver.  Does anyone have some advice or experience with this?

Besides the fractured hip/leg, you could not tell that anything is wrong with him.  Eats well, plays, etc.

Only other odd things I noticed since he was a kitten was:

Drinks a lot of water - Tested thyroid and Urine... nothing wrong.
Yawns - A LOT....
FIP/FIV/ Leukemia - Negative

Has anyone had any experience with  this this Liver issue or have experience with Siamese/Oriental Cat Breed problems?

Thank you

What does he eat?  Speaking as an Oriental Slave I don't think this is a breed issue.  (I have a Siamese Master as well)

Thanks for the reply.  He eats Natural Balance, which is a Grain free food and is a limited ingredient food - Green pea and duck.  Occasionally I give him some canned tune (in water).

I have a fourteen yr. old cat who has always tested with high ALT.  He also has had history of struvite crystals and because of that ate prescription Hills kibble from the vet for many years up until May of this year.  A couple years back, I tried giving him Denamarin, a liver supplement which is made of two ingredients, milk thiste and Sam-e.  His ALT numbers came down dramatically but I had to quit it because it made him vomit.  In May he was diagnosed with a primary liver tumor, which was removed.  He is doing well now.  Ask your vet about trying your cat on a liver supplement.

I wish I had continued iwth a supplement when we stopped the Denamarin.  He could have been given either/or ingredient.  I will always wonder if a supplement would have kept him from getting the cancer.
