DIY treat dispensing toy

I hate leaving Osa alone for hours at a time.  Mo and Ginger had one another, and the cats.....but Osa is pretty much on her own.  The cats are trying but still haven't warmed up to her.

I was looking for a treat dispenser at the store but didn't like any of them so I found this idea on pinterest:

Genious!  Pure and simple.    Use an exacto knife to cut a hole slightly larger than the treat.  Then fill it up and set it down.  Osa LOVES it.  I put an entire meal into the ball, along with a few soft dog treats.
