Little do they know, tunnels are much more effective when they are a) underground and b) not transparent. Good first attempt, kitties, but better luck next time.
From the submitter:
My dog's cone of shame wasn't quite long enoguh to keep her from licking an infected paw. I extended it with a plastic file folder and some zip ties, but ended up with a bit of a gap. The solution? A plate from an old motorcycle. Now everyoen can clearly see that this dog is, in fact, licensed.
