My 6 months old Birman cat had a blood test that showed that her liver function isn't good, some enzymes were too high (ASL I think). Vet accused me of feeding her bad food (Royal Canin) and said to feed her Hill's liver diet. Btw Royal Canin and Hil
It is unlikely that diet alone is the cause of significant decrease to liver function. I would agree that Royal Canin and Hill's are not very different in terms of dietary quality. I feel that starting on a liver diet at this point based on one blood test is very premature and that further diagnostics are likely warranted. Some possible causes of increased liver values including endocrine conditions, liver shunts, hepatitis, bile duct / gall bladder issues, liver / gall bladder tumors, or fatty liver disease. Depending on the nature and magnitude of the elevation, it may be insignificant as well if Maki's findings were not coupled with any clinical signs of illness. Some additional diagnostic testing to look into things more would be additional more specific blood work, radiographs, and ultrasound. Rather than dietary change, there are more target liver supplements. One that comes to mind is called Denamarin. There is a feline formulation available that would work fine. Hope t
