IT might be, but Metacam is still linked to kidney issues, and I wouldnt put a young cat on it if supplements will help them, best waiting till they are older or their body could get used to it. Zia is 19 and does have MEtacam a few times a week, but only after bloods showed her organs are in good health - she also wont take supplements, Molly will take Noractive, so she has that instead.
