Feline Lower Urinary Tract Disease. I am not feeding Science Diet I am feeding Hills Prescription Diet, because it is the ONLY food that keeps her crystal free and a healthy urine pH.. I realize you want to educate me on this but I assure you I have already tried it. The bottom line is, while the ingredients are not what I would want to feed any cat, the Hills Prescription c/d works at what it is made for, so I have chosen the lesser of two evils. A cat with a constant urinary tract problems vs a cat on a less than ideal food....I choose freedom from crystals for her.
<edit> Didn't mean to sound like a know-it-all or closed-minded, though I guess I did sound that way. It's just that I have been through other diets with her, and we always end up back on the c/d when the crystals come back and the pH jumps up to 7.5. She was on a canned diet when her trouble started, when she was barely a year old. Since then I have periodically tried to get her on high quality grain free canned diets, and it back-fires every time.
She gets a urine culture and blood work annually and all is well, as long as I feed her only the c/d. I'm not happy about it, believe me. But I have to go with what works.
