Many of the retailers that promoted free cat samples no longer do. There is no surprise that there is more dog than cat samples; however, these retailers offer discounts, coupons, or a chance to win a few items. If you stumble across pet stores that offer free sample boxes for cats, you must be lucky! There are no pet stores that offer free sample boxes that I know of.  You would have to pay a small amount and the shipping and handling fee. Buying samples boxes for your cat is not costly, depending on what they include, but most times, they send great products and items for your cat to test.
