Maru and the Aquarium

Maru the Japanese Scottish fold cat is ten years old, but he still loves his boxes, no matter what they are made of. His roommate Hana is all grown up, and still taking lessons from Maru. In this video, Maru confronts a see-through box, or what we'd call an aquarium. We can clearly see that Maru, like all cats, takes the shape of his container, and is therefore liquid.

By the way, a study to determine whether cats are liquid, solid, or both at the same time won an Ig Nobel Prize last night. You can read about all the 2017 Ig Nobel winners in this post.
