Cat owner runs a test to see if cats can pass through a narrow gap
by Mark Frauenfelder from on (#4QK4T)
There's a rule of thumb that says if a cat can get its head through a hole, its body will also squeeze through it. To test the rule, Maru and Hana's owners built a doorway barrier with a series of increasingly narrower gaps. I don't think they learned much from the experiment, but the video is entertaining.
