What happens if you compress cat food as much as physically possible? In this video, we use a hydraulic press and the Cubinator tool to create what might be the world’s densest cat food — a solid cube that smells amazing to greedy cats, but is almost impossible to bite or eat. We also test a similar cube made from dog food to see how an extremely enthusiastic dog reacts to an ultra-dense treat. The result: confusion, frustration, lots of licking, and very slow eating. No animals were harmed. All tools were cleaned thoroughly, and everything was done safely.
