In some entrances there is an apartment in which the grandmother of the cat lives. The smell of this apartment does not allow to live quietly all the entrance. And my friend got to get into the epicenter of this evil smell. He took away the room of his grandmother. You will probably think that he is a madman or, in the extreme case, a "smelling masochist" is much easier, the price was miserable, and the friend was not rich as a student, so I had to endure. Not long after he waited for his grandmother's next trip to his sister's village for a couple of days to host, he gathered all of this crowd in the amount of seven cats and twelve cats. You will probably decide what to melt, so probably thought and neighbors who saw this: ) here it is more difficult, a friend studied for a veterinarian, led his group to train in the skills of sterilization of cats and castration of cats.

After some time, the cats stopped targeting the territory in the apartment and the smell slowly disappeared.

That is how it is.)
