Underneath the cushion covers is pretty disguisting. Small toys, hairs, bits of biscuits and old cereal. Never any significant money, always just coppers.
We have mice in the house and finding their droppings in various choice places is not amusing. The cat is hopeless and will only catch and kill them outside. Had to stop using soap as they ate that. But we do use liquid soap instead.
dh is renovating our house and ds loves to play in the sawdust except sometimes he has an accident and so has wet trousers with sawdust stuck to them - lovely!
