I have noticed this especially with the Petco in my town. When I walk inside, I am immediately bombarded by dog stuff. There is a whole assortment of dog treats that look like cookies you would buy in a bakery, as well as a sizeable refrigerated section with fresh dog food. About 3/4 of the store seems to be taken up with dog food, toys, and supplies. There are a few aisles with cat food and litter combined tucked in a back corner of the store, and a just a few toys on the end of one of the aisles up front. I went in there one day just to find a pair of cat nail clippers and gave up. Petsmart has a few more cat items than Petco, but not much. I thought that just as many people (if not more) own cats as dogs, so what's the deal?
