Ritz only started doing this in the past 3 months (she is now about 18 months old)...we refer to it as "picknicking" ... taking pieces of kibble to a new location and chomping away. She is pretty good about licking up the crumbs.

The water dish is another matter....we finally 'nailed' it to a piece of plywood because she would pick it up with her teeth and flip it over, then play around in the resulting puddle.
