Osteoarthritis is a chronic disorder that deteriorates articular cartilage and periarticular structures, being a major cause of joint pain in elderly felines. Cats frequently develop arthritis due to aging, obesity, and a sedentary lifestyle – factors that are common in captivity. Therefore, arthritis in wild felines can be considered to be triggered by the same factors, given the similar physiology of domestic cats (Felis catus) to other members of the Felidae family. This study aimed to report a case of lumbosacral osteoarthritis in a lioness (Panthera leo). The 20-year-old animal from the Americana Ecological Park in São Paulo showed signs of apathy and hyporexia and was sent to the Veterinary Hospital of Americana College (FAM) for a check-up. The complete blood count was normal, while the biochemical profile showed slight hypoalbuminemia and a significant increase in amylase. Ultrasound revealed subtly irregular kidney contours. Endoscopy showed hyperemia in the respiratory tract and polypoid nodules in the nasopharynx. The larynx had bilateral subglottic ulcers, and the bronchi exhibited malacia and bronchial ring fractures. Radiography showed mineralization processes of the sternocostal joints and xiphoid luxation. In the spine, there were enthesophytes in vertebrae, ankylosing bridges, intervertebral foramen opacification, loss of articular facet definition, vertebral body remodeling, and mineral radiopaque structures overlaying the spinous processes. Therefore, it is concluded that due to genetic and evolutionary proximity, attention should be paid to signs of arthritis in wild felines as predisposing factors common in captive environments, along with advanced age, may trigger osteoarthritis similar to that of domestic felines.
