There is also a saying that yin and yang are not harmonious. Cats are yin and dogs are yang. If a man keeps a cat for too long, it will affect his personality and become too weak and indecisive.
If a woman keeps a dog for too long, she will become tough and emotionally fragile. Dogs are definitely younger than people, so women are easily hit. When an old dog is dying, it takes a long time for women to recover.
