People with a strong yin energy can keep cats. Cats are considered spiritual animals, and their strong yin energy can easily bring in supernatural things from the outside world, causing unclean things to accumulate in the home. If you must keep a cat, it's best to place amulets to ward off evil spirits. Furthermore, women with a strong yin energy are more suited to keeping dogs or other pets with strong yang energy, which can help balance the yin and yang energies in the home.

If a woman living alone with a strong yin energy keeps a cat, it may negatively impact her fortune and ward off unwanted romantic advances. However, if there is someone with strong yang energy in the home to balance the energy, keeping a cat will not have much of an effect. On the contrary, it can bring a lot of joy to the family and promote communication and harmonious relationships among family members.
