Cats that live mainly indoors tend to groom themselves more often. This can lead to excess hair in their stomach. They're also less active and tend to put on weight. Purina ONE, with BIFENSIS®, helps your cat develop less hairballs, have a lean and healthy body condition and reduced litter box odours. PURINA ONE® BIFENSIS® is a unique nutritional formula with beneficial functional bacteria scientifically proven to help support your cat's natural defences from the inside out. Developed by PURINA vets and nutritionists, PURINA ONE® BIFENSIS® contains, along with the beneficial functional bacteria, all the key nutrients your cat needs, including Omega 6 fatty acids. Its dual defence formula works in parallel on the inside, by helping to support your cat's natural antibody production, and on the outside by maintaining healthy skin and coat. Available in a wide range of tasty recipes with high quality ingredients, such as turkey as the number one ingredient, PURINA ONE BIFENSIS® helps support your cat's natural defences today and tomorrow. With fibres, proven to carry away twice as much hair from the stomach in just 14 days* *Purina research
