My cat likes to nuzzle my face in order to scratch her chin against the rim of my glasses, often knocking the glasses right off. I was thinking that I could hot glue some old toothbrush heads to some sunglasses, bristles pointing forward. The cat would then be able to affectionately bump my face while getting its face scratched.
Bad Invention time – I shall make ONE MILLION DOLLARS!!!
Credit to danny for the excellent name!
