Do these bags annoy you as much as they do me? Specifically I am talking about the long plastic 'strings' that are attached to the bottom of each bag to tie them up. My cats love to chase them across the floor as I open the bags and I am always scared that someone will swallow a piece. I always find too that they are no earthly use for actually tying the bags, not being strong enough. So I tear them off before I use the bag and throw them inside. I still occasionally find one that has somehow escaped onto the floor. Am I being paranoid?
