As a general rule, I think people who put their pets in little sweaters deserve to eat said pet's kibble. If we're going to blur the human/pet line, why not go all out? And if you're spending money on getting your cat a sweater, couldn't you be spending that money to put a sweater on some little orphan in Haiti?
Obviously, that rule doesn't stand when we're talking shark fins.
And at $34, you can afford to buy one for your cat and for some little Haitian orphan. Please, think of the children. The adorable little shark-finned children.
