The project consists of a series of architectonical, urban, and design interventions serving small animals which live in cities. The solutions include breeding shelves for pigeons, a corridor for hedgehogs, a ramp for small mammals, a ceiling panel with a sitting rack for birds, a water dispenser, a climbing curb, and a rescue hatch for rats. Every object has standardised dimensions and uses easily reproducible technologies. The set is accompanied by an instruction manual so that the objects could really help animals. The project was consulted with urban nature specialists, ecologists, biologists, ornithologists, and urban evolution researchers. It is directed to urban planners, officials, designers, and other people responsible for public space in cities.
