Maru is a large cat. His roommate Hana is also getting to be pretty substantial. Their human, mugumogu, arranged an experiment to see how small a passageway can get before the cats cannot get through. The opening is lowered gradually until we have to laugh at Maru's struggle to fit under eight centimeters. How low can they go? Watch and see- it will remind you of a limbo competition! One thing we can be sure of- they had some kind of powerful incentive to get through. Maybe it's the challenge itself.
