Why do the cat be the first in the house on the housewarming?

The most common tradition is the first to launch a cat in the house.  This sign is no longer one century.  Nevertheless, no one knows why to do it.  We in the Estate agent decided to figure out 😉:
 ⠀
 🐱 In the old days they believed that in every house it necessarily lives the house.  He was read as the owner and the keeper of the dwelling.  However, the nature of the house could be different, he may not like new tenants.  It was believed: whom the first house will see, on that he will releasing his evil.  Consequently, the optimal option was to insert the first cat in the house, which took upon themselves all the possible adversity of new tenants.
 ⠀
 🐱 Parapsychologists have his own explanation, why the cat's new apartment is first putting.  They can easily determine those apartment zones, where the energy is not very good.  Therefore, if some place in the house cat is bypassing, then people should not spend a lot of time there.  And where can the cat stay to sleep, you can put there and bed.  It will be the best energy place in the house.
 ⠀
 🐱 For another version, the cat was considered a symbol of wealth and prosperity.  For this reason, when they launch a cat to a new apartment, then wealth enters there ahead of the owners.
