My 12yro cat vomits excessively. Mostly after she eats or at least within a half an hour. I have taken her to the vet numerous times and they just give her a steroid shot. I have also changed her food to vet prescribed food but she will still puke. I love my baby but I'm almost at my wits end. My husband is ready to just put her down after ruining the carpet in the home we rent. I've read about giving her antacids so I guess I'm just looking for advice from other pet owners with the same issues...
