Animals that merely live in the house

Among the animals that live regularly indoors there are several which are interested neither in us personally nor in the stores of food and other commodities with which we surround ourselves. These include several animals that make use of the favourable conditions offered by houses. Some also use our houses as hunting grounds, feeding on the various invertebrate animals which they find there. As a rule these are animals which in the wild live in hollow trees, rock crevices or similar places.
