Petco and Petsmart were just about deserted, and Petsmart had plenty of litter left (I didn't find anything I needed at Petco). I bought 24 more buckets of litter and will pick up the original 24 tomorrow. An employee found a flatbed cart and helped me load up the van. He said he had been doing that all day, poor guy. The van handles very oddly with 840 pounds of litter in the back. . .
