This is because if it isnt a tornado... it cant be a bad sign, so basically only natural disasters like a hurricane or tornado could wind up a cat to hide under your bed or something with a low space where they would be safe other than the bathroom.

The basement (if you have one) would be most-likely safe for every living thing (DONT TRY TO SAVE A PLANT) hahahahhhh so not worthit but yeh you need to save yourself first even if your can flys up into the air... i would care for my pet. but i want to live too!! its your choice tho XD but back to subject
yes you need to just go look at your cat or dog and see what their reaction is to the weather. if a cat is looking alert, flicking its ears to sound, eyes open and then running away from you even if they do love you. this means many things but, when raining, means a bad sign of a tornado or other wind disaster. now if a flood warning comes, you NEED to save your cat unless it is already in a high place.

your welcome for the tip ^^ aaaand...other off subject stuffs :/ srry bout that...
