OK, my cat has been vomiting after eating occasionally for the past couple of months. I thought it was that the food was stale so I bought a new bag and that made things better, but she still vomits sometimes after eating Science Diet adult original. I notice she tends to vomit about 2-3 minutes after eating and drinking some water. I've been keeping the water fresh. The food she vomits back up is tube-like and has some chunks of food. Is she just eating too fast? I don't think she does this after eating everytime, just sometimes. Otherwise, her behavior is her normal kitty self (playful, attentive to the birdies outside, no weight loss, etc). BTW, I'm a 4th year med student so I'm just want to make sure I don't need to take her to the vet because she seems fine in every other aspect.
