Man Sees Cat Features in Human Faces
A 28-year-old man with palinopsia reports seeing feline eye shapes and stripes on people's faces, a case documented in the journal Cortex.

Researchers reported a 28-year-old man who sees features of his grey tabby cat, Luna, on human faces and human features on his cat. The case, documented in a report published in the journal Cortex, involves a condition in which earlier visual perceptions persist or reappear.
Why it matters
The case illustrates how damage to the right temporal lobe, a region critical to face processing, can distort face perception. Researchers say the findings add to a small body of documented face-distortion cases that clinicians may otherwise misread as psychiatric problems.
The report is a single-patient case study, with Karl's symptoms beginning two years ago after surgical removal of part of his right temporal lobe to treat an arteriovenous malformation. Duchaine's lab has heard from more than 250 people with similar face distortions, but the report does not state how many of those cases share Karl's specific cat-related pattern.
The players
Cortex
Cortex is a peer-reviewed scientific journal focused on the neuroscience of cognition and behavior, and it published the report on Karl's case.
The details
Karl, who lives in the northeastern United States, sees almond-shaped eye sockets, enlarged pupils and stripes on the faces of people he encounters, and sees the same features on his cat, Luna. Researchers prepared sketches and used a large language model to create photo-realistic images, which Duchaine and Karl then modified together for the report.
Timeline
1986: A Cortex study reported a woman who saw a poodle's face on every bus passenger nine months after a stroke.
Two years ago: Karl's recurrent palinopsia began after part of his right temporal lobe was removed.
2026: The report on Karl's experience was published in Cortex.
Culture Shift
The case echoes the 1986 Cortex report of a woman who saw a poodle's face on every bus passenger after a stroke, extending a documented pattern of animal-face perception following brain injury. It suggests that face-processing disruptions may produce recurring associations with pets and familiar animals.
Readers who live with cats may find the report useful for understanding how neurological conditions can alter perception of familiar animals. The report does not offer treatment guidance for individuals experiencing similar symptoms.
The takeaway
Face perception can be disrupted by brain injury in ways that link unrelated features, such as animal and human traits. Clinicians who encounter similar reports should consider neurological causes before assuming a psychiatric explanation.
