I wish they sold the tray separately so I had an additional one to swap out clean/dirty - but they don't sell it separately (parts). I refuse to pay $40 for a tray
I can't figure out how to use it because my diabetic cat likes her little "sister's" kibble, too. But maybe it's the one that keeps things cool? Nope, I see it's just for kibble. I am probably sleep-deprived from being woken up before dawn by the little cat that is hungry. Giving her another feeding before I go to sleep does delay her though. Thanks for posting this info though. Emmy
