Mystery tomato attacker

[mulemad]

Someone is eating a tomato in my kitchen. At first I thought it was a mouse. So I left a tomato on the table with no way a mouse or a rat could access it (unless it is a champion show jumper) and the next day the tomato had still been attacked. Could it be a nocturnal bird? There were no telltale rat/mouse droppings anywhere so I feel I need to look somewhere else. Or a Bat??? Last night I hid all the tomatoes with other veg: pattypans and padron peppers in a terracotta bowl and covered it with a teacloth. This morning The topmost tomato (a spanish gordo) had been attacked with a vengeance. There are teethmarks which rule out birds. But how could a rat/mouse get there and also leave no droppings. Back to the bat theory. There is an open loft area above the kitchen and I know there are bats (and mice). Does anyone have any bat experience? In the photos (last night's victim) you can see the teethmarks. The upper and lower incisors are 1cm (4/10 ") apart on attack. This bicho also leaves the skin.
