EDIT: Offer now dead.

You can sign up for the 20 day challenge (who knows what that is) and get a free bag of Puring One pet food for your dog or cat. They even have an option for those owners who have both cats and dogs, which eliminates the need to play favorites and only order a freebie for one of your pets! Although we all know dogs are so much cooler than cats anyways, so it doesn’t really matter in my household
