At my wedding, the cats were included in our vows. Pictures of our family-me, my husband and the Pet Products on all the tables at the reception to tell guests we'd donated money to an animal rescue group in lieu of favors.

So of course, four Pet Products hang on our fireplace mantle: for me, my husband, and for Harrington and Brady. Every year, I fill the cats' stockings with gifts - treats, toy mice, catnip, maybe a snazzy new collar. My mom usually sends holiday goodies for her grandcats, too. And I'm that person who buys gifts for my friends' pets. And I'm not the only one whose holiday shopping lists includes pets. According to the American Pet Products Association, at least half of all dog and cat owners will purchase pet gifts this holiday season - meaning 20 million people will spend a total of roughly $210 million. You don't have to spend a lot of money to give a thoughtful pet gift.
