Protecting your noggin from undesired electromagnetic fields and thought control requires something reflective, yet fashionable. Everyone knows that the tin foil hat has been the go-to choice for years (since at least 1926).
But it's 2018 now and only fools would craft their own headgear, because you can now just buy (a mylar) one from Archie McPhee. It even has a chin strap to keep it on your head.
Wait there's more! You can also protect your cat's head with its own miniature tin foil hat:
I'm guessing the cat version will also fit on the heads of American Girl dolls too. You can't be too safe.
