To mark his territory, a house cat from the small German town of Herdecke chose the most inconvenient place in the house to pee: into a power outlet!

The fuse was tripped because of the urine in the socket, as the local fire department reported on Friday.

When the emergency services were alerted at around 10:42 PM local time, they initially assumed that there was water damage in the apartment.

However, liquid was dripping from a socket.

They had no way of knowing that it was just cat pee: "No danger – but a rather unusual cause," the fire department wrote in a Facebook post translated to English.

After the firefighters had determined the reason for the alarm, the operation was complete after a short time.

"Sometimes, it really is the little things..." the department joked.
