i keep my bag-of-the-day on a small shelf, which is within reach for the kitties, but i make sure nothing is hanging down from the shelf, no tassels, no charms, no key fob, etc, to prevent attracting their attentionThe boys don't care about a bag until they see a tassel or a charm, then they think it's attack the bag time. I have mine on shelves in my closets, not always the handiest, but does keep little claws and teeth away.

strictly one bag out, all others are in the closed closet in their dust bags
