My 4 y/o cat has been vomiting ~2 times/day for 2-3 days. He appears perfectly healthy: active, purring, cuddly, though he has been a bit more vocal than normal. When he vomits it's usually soon after eating, and it's whole (wet) food, like he hasn't chewed. He is hungry right after, not phased a bit. He recently came off clavamox (short term, for sore gums). Should I be concerned or is he possibly just getting the meds out of his system, so to say?

Antibiotics can cause GI upset in cats, so it could be that Korben Dallas was eating less while he was on the antibiotics. Now that he's off the antibiotics, he's feeling better and eating much more quickly. That would be why he's throwing up all of his food. I would try to feed him smaller amounts more frequently to have him slow down his eating. If that doesn't help with the vomiting, I would take him into the vet for an exam, as he could have a medical illness causing the vomiting.

Poor Bean. It could be the azithromycin upsetting his stomach, as that could be a side effect of the antibiotic. I'd recommend giving the medication with food to see if that helps. Also eating the adult cat food can cause the vomiting. Sudden changes in diet can lead to it. Give his vet a call in the morning to let them know you are seeing some vomiting, as they may want to see him. Best of luck.

Vomiting could be caused by a number of things, including parasites, diet changes, toxin ingestion, infectious viral diseases, blockage in the intestines caused by ingestion of a foreign body, food sensitivity/allergy, decreased pancreatic function, or a mass/growth in the gastrointestinal tract. Please make an appointment to have Koko seen by a veterinarian to allow for diagnosis and treatment. I also recommend preventing Koko from running around/ playing for half an hour after meals and using a puzzle feeder/ slow feed bowl or treat dispensing toy instead of a bowl for feeding to get Koko to eat at a slower pace, in case she is vomiting due to eating too fast or running around after eating.
