Hi, New to the site. I have a 10 year old Siamese, always in perfect health and her recent physical exam was excellent with perfect heart sounds etc. however, when the bloodwork came back all looked good except high AST, ALT (around 500 each), previous bloodwork was perfect. She is eating, sleeping, and drinking normal, normal play and no vomiting except on occasion and usually has hair in it, occasionally all food. The Vet is suggesting to check levels again in 7 weeks, but still worried. We had been traveling just before her exam and she gets really stressed when we leave, plus she had Advantage Multi about three weeks before exam. She is indoor only and no other pets in the house. Any thoughts?
