My cat, Simon, has a bit of a weight problem, though he's not obese or anything. I can't skip giving him treats when I give my other cats treats, because that's not fair. So, I got these for all 3 of my cats. My Burmese Jake doesn't care much for them, although he will eat them sometimes, but Simon and my other kitty love these even more than their old treats.
Neither of my two cats would touch the lean treats. I left them there for hours, but no takers. I am now giving the packages away to friends in hope their cats are less picky.
