Are you aware of the accounting abilities of the crow? Did you know that the hedgehog is not a nice little one at all and that the dog perfectly classifies vowel sounds? Have you thought about why a cat's eyes glow at night? You will find answers to these and many other questions in a book dedicated to the biography of our well-known and nevertheless mysterious neighbors: cats and dogs, sparrows and bats, mosquitoes, frogs, lizards in ladybirds... In a word, the book describes the life and customs of the so-called synanthropic animals, that is, those who live with us next door - either in cities or not far from home, in the cultural landscape.
