Last night, I dreamed that a cat had a skin disease.

Usually cats are hairy, even if they have skin diseases, it is not easy to see them.

In addition, the cat may symbolize the little tiger, indicating that a big crisis is brewing.

In your dream, you dream that cats have skin diseases, which implies that you feel a huge crisis (cat-tiger) is brewing, and many ominous signs (skin diseases) have just begun to appear, but these signs are only known to you, and others don't know (covered by cat hair).

I hope it helps you.
