Once you open a big bag of cat food or kitty litter, you have no way of keeping it closed or of keeping the contents fresh and dry. Bag-n-Store portable storage sacks have foam insulation that helps keep freshness in and moisture out. The easy-pour spout unzips and folds out at the top of the bag. Padded handles provide easy gripping and carrying, and the handle on the bottom allows more leverage when pouring.
