Americans love their pets -- and that's been the secret to PetSmart's ( PETM) success.

>>5 Short-Squeeze Stocks Primed to Pop

PetSmart is one of the largest pet supply retailers in the country, with 1,250 large-format stores across the country. The firm sells everything from pet food to supplies and toys to smaller pets in its locations; it also provides grooming, training, and veterinary services inside its stores. More than half of PetSmart's sales come from consumables such as food, treats and cat litter. As a result, the firm has hefty recurring revenue generation. PETM also has a big advantage in its store size. While most grocery stores stock pet supplies, they can't offer the selection at a big box store that's only focused on pets. That keeps traffic coming into PetSmart.

How much Americans love their pets is another important trend for PetSmart. Consumers have been consistently increasing their spending on pets each year for decades. As pets get treated more and more like full-fledged family members, that trend is very unlikely to reverse. Expect that spending trend to continue to be a solid catalyst for PETM in 2013.
