A familiar electricist told me.

Calls the grandmother, says - in the room nothing in the socket is turned on, come, mother, look. I come. I cut off the plinth to see the wires. The smell of the cat will sweat everything. The grandmother says, "And I have a cat still in this place all the time writing and whispering strongly. "When the plinth is removed - my god! Everything has already rotted up there, and when the cat writes there, it must be striking quite strongly. That’s why he’s heartbreaking. But sucking there does not stop, constantly updating the label. A persistent animal.
