I get the feeling my vet may not be too open to alternatives.... they are carriers of the Hills brand... We'll see when I speak to them. There is a newer vet there who seems more open minded.
My vet is strictly allopathic and sells Hills also, but he has been willing to work with me on various issues. So, ask your vet (very nicely!) for other options besides the Rx food (which there are) and see what he comes up with.

I highly recommend http://www.holisticat.com/ and http://holisticat.com/forum/ as a wonderful resource for info on holistic health and lifestyle for cats.
