My 5 year old Cat was throwing up before being put on Denamarin. His liver enzyme level was real high. At this point we aren't sure if it is a tumor. Bubba had gotten real sick. He's been on the Denamarin for a week and is doing really good. He hasn't thrown up since being on it. Also I have been doing an IV twice a day for a week. Beginning today we have cut down to once a day.
