Question

What does the c & d stand for in Hill's Science Diet for cat with Urinary problems?

Answer 1

It stands for cystitis diet. It used to be that Hill's had a few different diets for prevention of urinary problems in cats but now they have the c/d multicare which covers both types of urinary crystals cats gets. Crystals lead to bladder stones. It also helps to prevent feline idiopathic cystitis, which basically means inflammation of the bladder with unknown origins. Those three reasons are the most common for urinary problems in cats.

Hill's is probably the most prescribed product for this but I don't have actual data just experience.
