The birdcage has the meaning of gathering wealth, but it needs to be placed in the correct financial position in family Feng Shui. If it is not placed in the financial position. It is like clutter and will affect your financial fortune.
Bird cages and animal cages (dog cages) have the meaning of trapped animals, so they are not suitable for placement in bedrooms for rest.
