EDIT: To those who are concerned about me using a blanket and not straw: thank you for your concern! I will be looking into getting something more waterproof for the box. If I can’t get something waterproof do not fear, the box is very close to where I will be during the storm and I will go out to multiple time to make sure the kitties are staying dry. Thanks for your help! ❤️ They’re super easy to make just tape a trash bag around a cardboard box with a hole in it. Make sure the edges are seale
