Hill's Prescription Diet Feline Oncology Care is a therapeutic dry food formulated for cats undergoing cancer treatment or recovering from serious illness. Supplied in a 3.17kg bag, it is intended for use under veterinary direction rather than as a general adult maintenance food.

The formula is calorie-dense to help cats maintain body condition and energy when appetite is reduced, with a nutrient profile developed by Hill's veterinarians and nutritionists to support cats with cancer. Palatability is a priority — the kibble is designed to encourage eating from the first bowl, which matters when nausea or treatment side effects make food less appealing.

Vets recommend this diet when a cat needs concentrated nutrition in smaller volumes without compromising taste. Owners choose it to help their cat hold weight and strength through treatment, when standard adult foods are not meeting the calorie or palatability needs.
