Her stomach won't settle unless she is kept on the same food. The vets will be able to tell you what the problem is if they've got anything about them. Ring them and ask if you can take a sample if you are concerned it's something more than an unsettled tummy!

When you go to the vets whatever you do don't let them palm you off with a prescription diet such as hills i/d.
