Due to recent advancements in squirrel to human translation technology, we know the squirrels are just as disgusted by the zombie plague: "Gus, you're hideous dude! Oh look, more delicious pine nuts..."
Until a cure is found, the public has been advised to lock their doors and hide their mixed nuts. Feeding wildlife and loitering on park benches is strictly prohibited within the hot zone. Be safe and survive. This has been a public service announcement on the ongoing ZSA (Zombie Squirrel Apocalypse).
