For the first week of Strombeek's diet, I discontinued the use of the treat ball. 
She is supposed to be restricted to 240 calories a day, but she had trouble getting that much wet food into her belly.
Then after the storming of both cardboard castles and burrowing her way into the kibble bag, I decided such determination was worthy of a reward.
1 feline greenie = 2 calories. I limit her to 10. She's got to exert at least that much hitting it around, right?
