Maybe it's an attribute of their name?
Same thing here: Sam gets a little Evo kibble if his BG drops too low, and for days after that he'll do everything he can to get me to give him that instead of wet food. It's like kitty heroin!
Seeing your updated signature - you probably already know this, but I would hold your current dose (or plan to do some extra monitoring) until you finish the transition off of the a/d. It's pretty high in carbs and once that is eliminated, you might see a decrease in BG numbers.
Do you know about fortiflora? It's a probiotic that you can sprinkle on the FF to make it more palatable. I don't know what magic they put in it, but Sam would eat a shoe if I sprinkled it with fortiflora!
