I do "stuffables" for my dogs' Christmas, but actually I do it all year round. Christmas I just make them extra good. I take hollow bones, kongs, and any dog safe stuffable item and pack it with goodies - peanut butter, yogurt, bits of meat, apple, carrots, blueberries, canned dog food, etc - and them freeze them. They get it as an after dinner treat when we want quiet time. So on Christmas, they all toys wrapped up so they can rip them open, and then they get goodies in their stockings like bully sticks or greenies or cookies. The cats get dehydrated fish treats and catnip (yup, they're druggies, it's sooo embarressing

).
What I REALLY want to do sometime for the cats is something like this...
