Seeing Things: A Community Science Investigation into Motion Illusion Susceptibility in Domestic Cats () and Dogs ().

Illusions-visual fields that distort perception-can inform the understanding of visual perception and its evolution.

The current study investigated pet dogs' and cats' perception of the Rotating Snakes illusion in a community science paradigm.
