the only thing I can say about cats and storms, is....
during one rain/thunder storm, Muffin got scared and hid under my bed, so I went in there with her, sat on the floor and pet her, talked to her, and the next time there was a storm, I guess she decided it wasn't so bad, she wanted to go outside!! well she had to settle for looking out the window with Cookie and me

those pics, how awful, scary!
