Wife and I got a cat from the shelter about 5 months ago now and when we took it to the vet, the vet didn't find any problems with it. However, soon after the cat started throwing up its food. We had a lot of theories as to why i.e. (playing right after so ate or ate to much). However, after observing the cat these past couple of months our theories don't hold up. The only thing I can think of is changing her food, but I don't think that will help because the cat throws up at random. It has thrown up right after eating or hours later. Also, 1-2 weeks will go but without a problem then all of a sudden the cat will throw up 1-2 times a day for a couple of days. We have not changed her food, feeding times, or amount. Any suggestions outside of changing food or taking the cat to the vet again?
