What weird household stuff does your cat like to play with?

Emily

My young cat loves the store bought mice (with and without catnip) and tearing cardboard. But lately she's been finding EVERY small household item too! Kitchen sponge, brushes, plastic lids, squishy parts of travel mugs, basically anything small. I'm fine with her playing with some of 'my' things, but some are just not safe or I don't want them destroyed.

What does your cat pay with?
