Wow! Thanks for the wonderful feedback. I'm new to this site and everything I have read on it is amazing. What a great group of people!

I guess I should have given more info the first time. Maggie was diagnosed with both Struvite and Oxylate crystals. With the help of a prescription diet, we were able to get rid of the Oxylate crystals. I have her on Phenylpropanolamine 2x a day (which has only helped slightly). This has been a problem since she was a couple months old, so I know it's not age related. We tried DES, but with no luck.

I will definitely try out that web site to see what they have, but with working and going to school, I just can't fit in a trip to Utah (although I would if I could).

Again, thanks a million for all of the information everyone has provided!
