Many dogs develop a slow erosion of the joints called degenerative joint disease, or DJD. But cats are also prone to DJD, especially as they age.

While the syndrome in cats is like that in dogs, the tell-tale signs are different. Dogs with DJD are often lame, but that’s uncommon in cats. Instead, affected cats are apt to struggle with grooming, jumping onto surfaces or negotiating the litter box. They may also be stiff and grumpy.

A number of conditions can cause DJD, including trauma or congenital defects. But one of the most important factors is obesity because of the extra stress it puts on a cat’s joints.

While DJD cannot be cured, the discomfort can be treated. So contact your veterinarian as soon as possible if signs appear. And remember that exercise and a healthy diet will help keep your cat’s joints jumpin’.
