I'm trying a lot of different foods right now to see if something really different from what I'm giving them would make they go cuckoo nuts for the food. The appetite stimulant DOES work - they scarf down their usual food (Natural Balance, Fancy Feast 1x a day as a treat; Whiskas Temptations or EVO treats) with no problem when they're on this Kitty Cannabis They LOVED the Trader Joe's canned chicken cat food - go figure! It is cheap, but the ingredients look pretty okay although no reviews by Petsumer Reports.
