I have been using the medium pet food container for a week. I purchased it, after reading many reviews of different types of pet food containers. I appreciate the locking lid, which prevents food spoilage, tampering and spillage by my curious feline friends. I appreciate it’s sleek, classy design. I like that I can leave it in plain sight in my kitchen or adjacent laundry room and that it does not detract from the aesthetics of those rooms.
