Cat Hippo Many Muscovites say that the ghost cat with Tverskoy is a prototype of the character of Bulgakov's novel. This well-bred and well-fed cat walks between the stations "Pushkinskaya" and "Mayakovskaya" along Tverskaya Street. It can be met only twice a month on odd days on an odd side. He walks out of the wall of one building and enters another. If you saw Behemoth on the way, then do not be scared - meeting with this black cat will bring you luck.
