There are many good cat food brands. Some of my favorites are Science Diet, Purina Proplan, and Royal Canin. They all should have an adult maintenance diet for an indoor cat. These three brands of cat food do extensive research on their diets and that is why I recommend them. However, there are many other great pet food brands out there in addition to these. The most important part about changing a cat's diet, is to do so gradually over at least about one week. If you abruptly change them from one food to another, you will likely cause them to get an upset stomach. Symptoms of this can be vomiting and diarrhea. That being said, there are numerous other causes of vomiting in cats including G.I. obstruction, parasites and secondary to kidney disease to name a few. These other causes will require treatment from a veterinarian. So if you were worried about Sammy, it is always a good idea to have her evaluated by a veterinarian to make sure that there is not more going on. Best of luck with Sammy

    It sounds like the change in food could definitely be a problem. It may have some ingredients in it (usually the main protein) that could be difficult for Sammy to digest. If his previous food was working well for him I would recommend try switching back and see if he still has the problem. If the vomiting is still consistent it could mean something more is going on and Sammy may need to be checked out by your vet.
