so far so good, first day he ate it as usual but the past few days (we're on day 3 I believe) he hasn't eaten any.. that I know of. He goes over.. gets close and sniff / inspects it but doesn't gobble it down. I tossed a bunch that I let "tempt" him for a couple days and he ran around looking for it and going back to the spot were it was... which was weird.. so we'll see!
