The article tries to apply the methodological conception devised by Bruno Latour for research into relations between man and animals. The reflections concern a concrete group of animal owners who breed pedigree cats, and with whom the author has been cooperating for a number of years. The Latour mythology proves to be of help for analysing a 'project' involving the cat, an ideal representative of the species in the eyes of its breeder. At the same time, it discloses discrepancies contained in the very idea of the possibility of designing an object of culture as complicated as a living animal. Pedigree cats are something more than the sheer dreams of their designers, and biology turns out to be a partner and not a passive substance. The text refers to the traditional objects of interest of cultural anthropology - the relations between man and the natural environment.
