I'm pretty sure that it is the generic version of Metacam?
My vet, who only deals with cats, goes to lots of cat seminars etc. She said the latest studies show that it increases the lifespan of older cats - partly due to increased appetite and also because it increases mobility. Just the usual precautions - that they eat before having a dose and that the max dose should be for a cat's expected lean weight - so in otherwords, if a cat is overweight, it should be dosed on what it's bodyweight should be, rather than actual. Kylie was on 1/2 dose and Alice before her, was on the full dose for several years.
