The reasons why cats have white dander:

1. If there is not much white dander on the cat, it is caused by the dead skin during normal metabolism.

2. It may be that the cat has not been bathed for a long time, has been bathed frequently, or has not rinsed the shampoo after bathing, which will lead to the appearance of white dander on the cat. It is recommended that the owner take a bath once a month in summer and once every 3 months in winter, and rinse the shampoo thoroughly.

3. It may be that cats may have white dander on their bodies after being infected with fungi, bacteria, or parasites. It is recommended to remove the hair for microscopic examination to determine the cause and apply ointment.
