“…There have been the reports of that chimpanzees experience visual illusions such as the illusion of brightness (Gunter, 1954), the Ponzo illusion (Fujita, 1997), the Müller-Lyer illusion (Suganuma et al, 2007), and the corridor illusion (Imura & Tomonaga, 2009). There is also evidence that pigeons experience visual illusions.…”

We present the first evidence that cats experience visual illusions and that a non-human animal can see illusory motion. In three videos we show cats reacting with hunting behavior when watching the Rotating Snakes illusion. This is taken to mean that cats see illusory motion in this image due to the propensity of cats to pursue movement. This is further supported by a survey where 29% of the respondents answered that their cat reacted to the illusion. A number of preferential looking experiments were also indicative of cats experiencing the illusion, but not conclusively so.

“…Although most previous investigators (1)(2)(3)(4)(5)(6) have used stimuli as large or larger than those of this study there has been considerable variation in the distance from the stimuli at which the cats have had to make a discrimination. All studies in which the cats were allowed unrestricted approach to the stimuli gave positive results (4,6).…”

Cat Color Vision: The Effect of Stimulus Size

Adult cats were trained to discriminate blue from green and gray. Although the cats could discriminate the intensity of stimuli whose areas ranged from 33 to 0.36 square centimeters they could not discriminate color when the stimulus was 0.36 square centimeter (less than 20 degrees visual angle). This influence of stimulus size may account for both positive and negative results of previous studies.

“…Although color vision of the cat has been studied electrophysiologically2, 22,26) as well as behaviorally, 6,9,11,18) no positive evidence for color vision of this animal has been obtained, despite a series of work by Granit,8) whereas they showed only a weak response to white light.…”
