Have a 16 yr old short hair cat. "Knee" joint on front leg

Customer Question

Have a 16 yr old short hair cat. "Knee" joint on front leg is swollen. She walks with a limp but still jumps on furniture. She lifts foot whenever sitting. This happened last year also but resolved spontaneously. This episode has lasted for several weeks. Arthritis perhaps? Any OTC treatment or analgesics available?

You're correct to suspect osteoarthritis at Cleo's age which is severe enough to cause joint effusion - excess joint fluid. The main differential for such swelling is a synovial or bone cancer but such cancers don't come and go. Aspirin (NOT ACETAMINOPHEN) is safe at 5 mg/lb every 72 hours but often isn't tolerated long-term in cats. Ibuprofen and naproxen are toxic to cats and must be avoided. Consider a neutraceutical such as feline Dasequin (please see here: http://www.amazon.com/Nutramax-Dasuquin-Capsules-84-Count/dp/B001ICRYTY) as well as the omega-3 fatty acids in fish oil which I dose at 20 mg/lb daily of the EPA in a cost effective generic human fish oil product. EPA is the most antiinflammatory of the omega-3 fatty acids.

If you didn't see a positive change within a few weeks when dosing her as above, X-rays of the joint are indicated. At her age a newly emerging cancer is possible. Please respond with further questions or concerns if you wish. I have to leave my computer for a few hours but I promise to reply as soon as I return if need be.
