Canine ESP – an awareness of information about events external to the dog itself not gained through normal senses and not deducible from previous experience. While ESP can refer to a dog’s clairvoyant nature (its ability to see future events), tin foil hats protect against telepathy (a dog’s ability to read your thoughts).

This is important if you have an outdoor cat. Getting tin foil hats protects the cat’s whereabouts from directly being discovered, and from your own mind being queried about where you think the cat is located.
