While cats don't develop hip problems as frequently as dogs, they are still common. Cats, however, mask pain well enough that their hip problems are easy to miss. When identified, however, hip problems are usually treatable.

Types
-
Cats with hip ball joints that don't fit properly into their sockets have feline hip dysplasia (FHD). Both osteoarthritis and rheumatoid arthritis can also affect cats, according to the Arthritis & Glucosamine Information Center.
Symptoms
-
FHD and arthritis share several symptoms, including a reluctance to walk or play and limping. Arthritic cats may be feverish, generally lethargic and uninterested in food.
Causes
-
FHD is genetic. Kittens inheriting it gradually develop symptoms as stress on their hips dislocates the ball joints. Deterioration of joint-cushioning cartilage causes osteoarthritis; rheumatoid arthritis occurs when the immune system attacks the joints.
Treatment
-
Neither FHD nor arthritis is curable. Surgery treats severe FHD cases; pain medication and glucosamine supplements, mild ones. The anti-inflammatory pentosan polysulfate sodium can rebuild cartilage in arthritic cats.
Prevention/Solution
-
Keeping your cat at a healthy weight will lessen the stress on his hips and other joints, and reduce the pain of arthritis or FHD.
