My cat Pita has been throwing up a lot lately, probably once every 2 to 3 days, a short time after eating. He's been throwing up his food now and then for about a year, but never with so much frequency. It's food and liquid, no hair. We feed him a small bit multiple times a day throughout the day, no huge meals. He acts like he's hungry ALL the time, but he's not losing any weight (he's a bit heavy, but I assume that's because he's hitting middle age), so I haven't been real worried about it. He is 9 years and has short hair. Last time we took him to the vet (less than 6 months ago) he was pronounced quite healthy. I'm thinking of just taking him to the vet again, but I'm open to your ideas about how to stop this too.
