  • Septic arthritis occurs when bacteria or another infectious agent is introduced into one or more joints, leading to painful inflammation. The signs of septic arthritis include heat, swelling, and pain in one or more joints. There is typically decreased range of motion in the affected joint(s), as well as fever, lethargy, and lack of appetite. This handout discusses causes, signs, treatment, and follow-up care.

  • Approximately 20% of cats across all ages suffer from painful osteoarthritis in one or more joints, and 90% of cats over 12 years of age show evidence of arthritis on radiographs. Because cats are living longer, every cat owner will face the issue of osteoarthritis at some point. This handout discusses the use of nutrition and nutritional supplements to aid in the management of your cat's osteoarthritis. Weight loss, omega fatty acids, and various chondroprotective supplements are discussed.

  • Osteoarthritis is a common condition affecting bones and joints in many older cats. It is a disease of management and cannot be cured. Medications, physical therapy, nutrition, and surgery may all be considered to help alleviate the pain. Cats can live a normal life with a tailored care plan.

  • Degenerative joint disease is arthritis caused by deterioration and degeneration of tissues lining joints. It is an under-recognized condition in cats. Treatment involves modification of the home environment, regular gentle exercise, anti-inflammatory drugs and other medications, omega fatty acids, chondroprotectants, and possibly other nutraceuticals. Maintaining your cat’s weight can help prevent degenerative joint disease.

  • Pentosan polysulfate sodium is an injectable disease-modifying osteoarthritis drug (DMOAD) used to treat non-infectious and traumatic arthritis in dogs. It is also used off-label in cats. Follow your veterinarian’s instructions on how to administer the injection and dispose of the needle and syringe appropriately. Side effects are rare when given according to label recommendations and at prescribed intervals. Do not use in pets with a known hypersensitivity to it, in pets with known or suspected bleeding disorders or immune-mediated arthritis, or in pets with severe kidney or liver disorders.

  • Polysulfated glycosaminoglycan is an injectable disease-modifying osteoarthritis drug (DMOAD) used to treat non-infectious and traumatic arthritis in dogs. It is also used off-label in cats and small mammals. If administering this medication at home, follow your veterinarian’s instructions and dispose of the needle and syringe appropriately. Side effects are rare when given according to label recommendations and at prescribed intervals. Do not use this medication in pets with a known hypersensitivity to it, in pets with known or suspected bleeding disorders or immune-mediated arthritis, or in pets with severe kidney or liver disorders.

  • A luxating patella is a kneecap that 'pops out' or moves out of its normal location. Signs include intermittent lameness, an unusual 'skipping' on the affected leg when the cat walks or runs, or difficulty jumping. A luxating patella can be corrected surgically, especially if the patella luxates frequently. If your veterinarian performs surgery before arthritis or another knee injury occurs, the prognosis is excellent.

  • Perna is given by mouth and is used over the counter to treat inflammatory conditions such as arthritis in cats, dogs, and horses. Give as directed by your veterinarian. The most common side effects are gastrointestinal effects such as nausea and diarrhea. Do not use in pets that are allergic to it or other shellfish, or in pregnant or nursing pets. If a negative reaction occurs, please call your veterinary office.

  • Methylsulfonylmethane is given by mouth and is used over the counter and off label to treat inflammatory conditions such as arthritis. Give as directed by your veterinarian. Side effects are uncommon but may include stomach upset, restlessness, or tiredness. Do not use in pets that are allergic to it or that are pregnant or nursing. If a negative reaction occurs, please call your veterinary office.

  • Osteoarthritis (OA) is a progressive, degenerative disease that worsens over time. This handout discusses steps you can take to help your cat deal with osteoarthritis (OA) or degenerative joint disease (DJD). In addition to medications that may be prescribed by your veterinarian, other treatment options such as weight loss, exercise, and complementary therapies such as chiropractic and physiotherapy are outlined.
