@Gargron sometimes playing cards with my mum one of my cats will get behind her hand and she will ask him what she should play. Then he will move his head towards a card and she will play that card. The funny thing is when this has happened she usually wins. But he’s so much fun! Very smart and clever (in this way it’s just playful but he works with the dogs to get treats and one of them will go get him for the same reason).
