Believe it or not, there’s actually a neurological disorder called Capers syndrome, which is where the sufferer becomes convinced that someone close to them has been replaced by an impostor. Now Harvard neurologists R. Ryan Darby and David Caplan have identified a variant of this mental disorder nicknamed Cat-gras Syndrome where a man became convinced that his cat had been replaced by an identical cat with a different personality.
The 71-year old man with a history of heavy drinking and head trauma from ice hockey became obsessed with the idea that his pet cat had been replaced by an imposter cat that was involved in a conspiracy against him.
