For the Nutritional Management of Cats with Dental Disease As your cat ages, dental problems become more likely. In fact, by age three many cats are already showing the signs of dental disease. Brought on by a build-up of plaque and tartar, dental disease can cause painful and even serious problems. Prescription Diet Feline t/d was formulated specifically for the nutritional management of cats with dental disease caused by plaque and tartar build up in cats. If left unchecked, this build-up can lead to gingivitis, a dental condition that can weaken the gums and tissues that support the teeth. ONLY AVAILABLE IN AUSTRALIA - QLD, NSW, VIC AND ACT
