Source: The story's main character is a 13-year-old boy named Darek living in
Warsaw. One day, he rescues a
black cat from a group of violent youths on his housing estate. It turns out that the cat can actually speak and introduces himself as Rademenes. Grateful for being saved, the cat offers to make Darek's seven
wishes come true, one wish each Wednesday, and one for each episode. At first, the boy doesn't realize the power of the cat's gift and his wishes are selfish and superficial. Rademenes quickly becomes Darek's friend and enjoys granting his wishes. He cheers the boy up in hard times, and he in turn takes good care of the pet, keeping his
supernatural abilities a secret from everyone. In episode 6, it turns out that the cat used to live as a human in
ancient Egypt, and was punished to
reincarnating as a cat for millennia because he had revealed the
heliocentric theory and explained the effects of
solar and
lunar eclipses to the people. In the final episode, Darek's last wish is for Rademenes to turn back into a human. The cat vanishes, but then reappears as a man named Senemedar (Rademenes spelled backwards) who happens to be a co-worker of Darek's father. ==Cast==
