No. Cats are very special alniams. They have a unique body biochemistry and liver function that makes NSAIDS especially dangerous. Cats do not have enough of the enzyme bilirubin-glucuronide enzyme. That fact makes the NSAID linger in the cats bloodstream. If you must give an NSAID, it is best tolerated by the cat to give meloxicam and ketoprofen in limited doses, less frequently. Also, since these medications are VERY tough on the stomach, give the cat cimetidine, ranitidine, famotidine to coat the stomach 20 minutes prior to the NSAID. AS ALWAYS, CONSULT A VETERINARIAN BEFORE GIVING ANY MEDICATION.
