Is this cat photo real? If so, how was it done?

The first rule of cats and boxes:

Boxes contain cats.

Definitely.

I would amend this to state that anything flat will be covered by a cat, and anything with space and defining boundaries will contain a cat. YMMV.

Maybe it just LOOKS like the baskets are precariously stacked. It would be really easy to nail together a totem pole using the baskets, then secure the back of it to a wall, turning it into a cat-fortress which isn’t able to be knocked over. Cats could jump in and out of something like that at will. It’d just be a matter of waiting for all of them to be in it.

Catching seven cats all in motion at the same time? Impossible.

Catching seven cats all lying around doing nothing at the same time? Not hard at all.
