Review: Zukes Hip Action Supplement Treats

I got Zukes Hip Action Supplement Treats in Carly's one and only Pawalla box last month.  I like that it helps the joints in the hips and knees but Carly, after a few days, turned her nose up at them.  I would split them in half and give them to her that way but she spit them out so I threw them away.  She'd rather have her urinary tract supplement treats instead, and her feline greenies, which I have to get more of.  I'm thinking maybe she smelled the good stuff in them and didn't care to eat them, the hip action supplements, who knows?
