Cats Vs. Paper Bag, Paper Bag Wins (VIDEO)

It's probably not a good idea to leave your pet cats to play with a paper bag, but if you are hellbent on doing so, it's probably best to leave a digital camera running to catch the ensuing cuteness.

Fortunately, YouTuber 'shironekoshiro' has saved us all a bit of time by doing that for us already, capturing footage of two of his beloved pusses crawling in and out of a paper bag and being utterly adorable throughout.

Aside from being very cute, this video also stands as further proof that the feline species is addicted to all things cardboard and paper. For proof, just take a look at this video gallery of cats playing with things - often of the paper persuasion.
