They provide a more predictable response, a faster response, but unfortunately they have some side effects, primarily gastrointestinal upsets. The two drugs most commonly used in dogs are Rimadyl and Etogesic. Very, very rarely, Rimadyl can cause liver problems, but I still recommend a blood test for liver function before treatment, and then again after about a month of treatment. Fortunately, the liver problems are very rare and the side effects are reversible once the drug is stopped. Fortney said there are drugs from the same group specifically for cats.
