At his annual checkup his blood values were off. He has cycles where he eats fine for a few months, then starts throwing up and his appetite diminishes. I wanted to wait on retesting until he was in his vomiting phase in hopes that we can figure out what's going on. He is 10.34 lbs. so missing a day or two of meals isn't good at all. He has been very quiet these last 2 days, very unlike him. We leave in an hour so please send good vibes our way,
