Osteoarthritis in cats.

Osteoarthritis is a common radiographic finding in older cats, with a prevalence of up to 90% in appendicular joints. Many cats experience impaired mobility from osteoarthritis; however, there are more and more treatment options available, including diet modification, environmental modification, medical therapy, and physical rehabilitation. Continuing challenges involve accurate diagnosis and outcome assessment of treatment, but considerable progress has been made in the last decade.
