Just a side note--
some of the freeze dried treats are hard/splintery.... we usually get the dogs ones because it is the same and they are less expensive (1 ingredient)
Mine would eat too fast and puke-I started putting them in the vita mix and turning them into fairy dust like consistency and it also releases the smell.
I use the pure bites in our auto feeder for night time snacks-mine only like pure bites chicken.
Orajen is also a popular one here--wild boar is one of the popular ones and mine like the beef as well.. (Orajen is not hard like pure bites)
I don't know how carb sensitive your kitty is but sometime I give 1 or 2 kernels of the waggers 12% carb for a pokey treat (mine is not that carb sensitive)

Another one that is like crack is bonito flakes (if your kitty likes fish)

Stella and Chewys and Natures Variety and Primal all have soft freeze dried food that can be used as a treat.
