Your cat's health and activity are often linked to healthy joints. Cats with osteoarthritis (form of osteoarthritis in which the cartilage in a joint wears down) show subtle behavioural changes. They move less (climbing, jumping), wash themselves less often and suffer from involuntary urine leakage. Treating cats with osteoarthritis often requires drug treatment. However, the right nutritional support (adapted diet food) can also make a difference for your cat.
