If you have pets, you need to make sure to include pet supplies in your storm shelter or bunker. It will be too late to go back and get them once you are down there and you will have a serious issue if you have to go without. Just add a few simple supplies and you will be ready for a disaster.
You need to have food and water for your pets, along with bowls. You should also have a carrier or kennel in case your animals get upset. In addition, you need to have a system for them to go to the bathroom. You can use a disposable little box for cats. For dogs, you can use puppy pads. Just make sure you have a way to dispose of the litter and the puppy pads.
Be sure to stock up on these supplies so you will be ready for a disaster.
