There is no altruism among house cats. It's every cat for himself. You could say it's a dog-eat-dog world, but that would be silly. GM put a heating pad underneath the cats' little sleeping house to counteract the cold weather, and documented what happened in pictures.
To share with everyone, GM put them into a new Tumblr called Cat Wars. We hope to see more of the competition between the two over the highly-coveted heating pad! -via Uproxx
