We have already been the prescription food route.. It was a waste of money, as were the other ultra-expensive kitten foods the vet had us try. We have tried them all; Both at the vets, and at the pet shop as well. Each food has been given a month's trial (or more). She has a diagnosis of colitis, but that is just based on the symptoms, and her stool samples.

I am aware that the senior foods are not as nutritious as the kitten foods, but if the senior foods can stop this water for stools, she will be getting more nutrition from the senior food than she has been from the kitten foods with this problem.
