mouse in house

My keen powers of naturalistic observation have brought me to the conclusion that we have a mouse in our house.

This morning, Maurizio asked why a piece of styrofoam with which he had plugged into a hole in the baseboard behind the stairwell door had been removed from said location and lay on the floor immediately in front of the hole. 'Tis a puzzlement!

Sadly, Georgia was not here to assist with this detective work as her level of hysteria sparked at the appearance of small furry animals exceeds that of Oma!

After lighting my pipe and donning my hat, a gander down the hall found tell-tale signs of various shredded items such as the aforementioned styrofoam and a suspicious remnant of black rubbish bag, led me to a preliminary hypothesis of rodent presence. Closer inspection revealed one final, albeit tiny, confirming clue.

Logically, this means we NEED A FELINE!
