If you have an older cat that suffers from arthritis, you might be tempted to give your  pet pain medication from your medicine cabinet.  Stop right there! Medicine such as aspirin, acetaminophen and ibuprofen are toxic to cats.  In very rare instances, some veterinarians will prescribe aspirin for cats but only in tiny amounts and on a very specific schedule. Most veterinarians prefer other methods to treat arthritis in cats.  They would recommend inflammation reducing agents such as Glucosamine instead. They may even recommend rehabilitation treatments such as acupuncture.  In most cases these therapies tend to work best. Always consult with your veterinarian and never administer any pet medication without his expert opinion. Remember, your pets count.
