If you lost a cat in your house, do not rush to panic, walk, and loudly shout out his nickname, get under all the sofas and cabinets with a flashlight. And even look out into the street from the open window.
Perhaps your beast decided to change the place of habitual habitation and hide in the most prominent place, where he never hid.
Now this is his favorite place, because there is heat from the lamp and it's hard for me to reach it. )))
