My cats are in a bad mood because of the weather. What can I do?

[Kibara]

How can I tell them I am not the Weather Goddess and have no control of it? It's going to be raining for 9 of the next 10 days, according to the Weather Channel's Website.....
When I came home, my male cat was on top of the cat tree and he turned his back to me. Trust me - they are really not happy because there is a lot of thunder and lightning and they can't go out.
