Arguments with Pathos

In the advertisement that I chose, there is a cat standing there on two of its paws.  Based on how the cat is standing, the viewer is supposed to assume that the cat has to go to the bathroom.  The advertisement is for Fresh Step cat litter, and the tag line is: "It's hard to find your litter box if you can't smell it."

This advertisement uses humor to sell their product.  First, the viewer is distracted by the cat's odd, human-like behavior and then laughs when they realize it is for litter.  Unlike some humorous ads or bumper stickers, this one is not meant to offend or put down anyone.  Arguments with humor are a great way to get your product to sell.  Funny ads grab your attention and help you to remember the product.  Also, the tag-line cues into the important qualities that you want for your cat litter: no smell and not being able to find the litter box.
