My cat is too persistent. If he goes to the toilet, then buried until they are removed or until the shoe comes in. In the middle of the night, his stubborn scratches with his nails on the floor generally bring everyone in the house.
The night. Everyone is sleeping. Here, in the hallway, the cat begins to bury a cup, hoping, apparently, that he will still succeed sooner or later. I am lazy to get up and I scream to my daughter:
Look what the cat is digging!
In response an angry voice:
He is digging his own grave!
