“Safety is our number one priority.”
So, we tried it. At first we failed, because we used an American can, which is no doubt much sturdier than the crappy tin used in the video. After finding a Russian can of tuna, we had better results. The can exploded sending tuna everywhere, and we spent hours in the emergency room afterwards getting a couple of fingers stitched back on, but we were successful, and our cat is now happy that he will survive the zombie apocalypse.
(Disclaimer: You don’t really think we would be stupid enough to try this, do you?)
