We moved to a new house a few weeks ago. Last week I noticed an apple in a bowl on the kitchen counter was partly eaten. Today when I got home, in the bowl one apple had quite a bit taken out of it and a few other apples had small slivers taken. I searched the kitchen for signs of mice (chewed wood, droppings) but there was nothing. No other signs of infestation or wildlife. Anyone have any idea what is going on? Poltergeist?
