I got this kitten, several weeks old, about two weeks ago, and for the first few days she had diarrhea. While this went away, in the last two days she has now vomited twice. After the first time (in which she threw up what looked like the cat milk we had given her), we assumed it was the type of food and switched to a different type. All seemed fine until just a few minutes ago, when she vomited up the food she had earlier.
Everything else seems fine; she runs around and plays, has a good appetite, and she is no longer having diarrhea, so what could be the problem?
