If his ALP is high than it might just be from his Cushing's disease. If the ALT is high, you could ask your vet about trying Denamarin and see if the helps. It is very encouraging that he is acting fine and eating ok.

    His high liver values are likely due to the Cushing's disease for which the Vetoryl is given. Excess cortisone production of the adrenal glands (Cushing's Disease) will make the liver enzymes go up. This does not necessarily mean that Tigger's liver is damaged, so your veterinarian is right not to do anything else. You can give Tigger a liver function supporting milk thistle preparation, however consult with your veterinarian first about whether he thinks it will make a positive impact.
