PRO PLAN® FortiFlora® is a probiotic complementary feed that supports the digestive health and overall wellbeing of cats and kittens. It helps balance the intestinal microflora and supports the immune system, especially when a cat has digestive upset caused by stress, antibiotics or a change of food. FortiFlora® helps improve stool quality, ease digestive upset and can also act as an appetite enhancer for cats with a poor appetite. Consult your vet before use.
