Auggie,

I tried going from Science Diet to Purina One to save a little $$$. My Bubba, Casey (RB, 2002) got an instant UTI. It ended up costing me MORE money. So much for that!

The first thing my vet asked was if I had changed brands of food. She also told me that some cats are more susceptible to UTI's and urinary crystals than others.

Boy did I learn my lesson!!

Hope Phoenix is home and well soon!!
