Pet's info: Cat | Red Point Siamese | Male | neutered | 10 lbs

Hi, I believe my cat has a stomach ache, most likely from overeating. We were leaving for 1.5 days and left out two days of food and he ate it all instantly. When we got home he looked sick and he threw up on the carpet (looked like mostly his dry food). He was very lethargic, weak, and did not want to leave his bed. After 24 hours of not eating we tried to feed him wet food but we regurgitated the food an hour later. He seems to be getting his energy back, but we are worried about him not eat

Hi, I think it would be a good idea to have Snowden checked over. He might be suffering with a touch of pancreatitis.It could also be just a tummy upset from eating too much, but some medications will help him get back on truck promptly.
