Weight reduction
Just like the human epidemic, almost 50% of the pet population is overweight. Even a little extra weight can impact the pet's quality of life and relationship with family because that extra weight can reduce play time, impact mobility and affect the lifelong general health of your cat.

Hill's nutritionists & veterinarians developed Prescription Diet® r/d® clinical nutrition especially formulated to support your cat's weight management. In fact, r/d is clinically proven nutrition for healthy weight loss in just 8 weeks.
