The Winn Feline Foundation just released some interesting news on osteoarthritis (degenerative joint disease) in our favorite felines.
"Osteoarthritis, or degenerative joint disease, is a common cause of chronic pain in middle-aged and older cats. It is now known to be much more common in cats than previously thought. Clinical signs include unwillingness to jump, stiff gait, decreased grooming, house soiling, irritability, and hiding. Unlike dogs, lameness is not necessarily a common clinical sign of osteoarthritis in cats. Elbows and hips are most commonly affected, and many cats have disease in more than one joint. Pathologic changes, many detectable on radiographs, include deterioration of articular cartilage, osteophyte formation, bone remodeling, soft tissue changes, and low-grade nonpurulent inflammation. Treatment includes weight reduction if applicable, and environmental changes such as making the litter box more accessible. Medical therapy may include nutraceuticals, non-steroidal anti-inflammatory drugs, and analgesics. Non-pharmacological interventions include passive range of motion exercises and acupuncture.".
