When all else fails to amuse your cat, you can always rely on a paper bag to do the trick.
Cats love for you to buy really expensive, fancy cat toys so they can make you feel like a right dicky-doo-dah when they play with paper bags or pipe cleaners instead.
They also like rolls of toilet paper. But you’ll be sorry if you allow that.
God’s stuff works; except cats, because they prefer to watch humans work. 🙂
