I have 2 big furry cats that we love so much! I try hard to find good deals on cat food and litter whenever I can. In the SmartSource 7/25/10 it has an ad for a FREE 7 to 8 lb Bag after Mail-In-Rebate! A value of $12.99. To download your rebate, visit www.BuyTheBestTrial.com! I just filled out a form and opened a pdf. We are looking for a low dust formula.
