The cat Kaiser and the dog Nana once went head to head in a competition to see who was the best trained animal around. And now, years later, they've teamed up to show a pair of rats named Raven and Famous who's boss. But, for sheer number of tricks, the rats win. They also win by having adorable tiny props for theirs.
On the other hand, the dog taking out the garbage is way more efficient than the rats.
