my cat threw up a small amount on saturday night and again this morning. this morning he threw up a significant amount and i noticed some unchewed food. i arrived home late last night and angus was hyper and VERY vocal for more than two hours. i gave him attention, but he didn't calm down. i'm wondering if my late arrival upset him b/c in august i was gone for ten days. maybe he thought i was leaving again? this morning he kneaded at my arm before i got up. he is still active, but felt warm. i plan to call the vet at 11, but i was wondering if anyone had any advice. i didn't give him his treats this morning.
