Do we not have a tag for the Cone of Shame? I tried a few variations, but if it's already there under a more formal name, I failed to figure out what it was.

EDIT: Never mind, found it! It's pet cone. Either it oddly didn't come up in the autocomplete suggestions when I started with "cone", or I just overlooked it. Either is entirely possible. Helpfully, it's aliased from "Elizabethan collar", which I finally remembered is the proper name of the device.
