Lol, groceries in the freezer! I got myself all wound up the first couple of times and ended up pricking myself, dropped rice all over the floor, then got a nice bead of blood only to have Java Shake his head and get it all over my face!
Give yourself and kitty a little break, have some cuddles, give him a carb free treat, and give it another go in 15 minutes!
I'm promise you, you will get the hang of this, and so will kitty. Java now hops up to his testing spot randomly throughout the day for a test! He gets a treat afterwards.
Don't sweat it, you can do this!
