This is most unfortunate since most pet owners would certainly want their pets to survive alongside them, regardless of whatever disasters they face. You can improve your pet's chances of survival by packing these useful items for your pet's first aid kit. (h/t to JustPlainMarie.ca)

First aid book for cats and dogs

A first aid manual for pets can go a long way in instructing you how to apply proper first aid to your pet in case of emergencies. Ideally, you should already be reading this book and familiarizing yourself with basic concepts before a disaster, rather than during it. If you want to take it a step further, you can even attend a first aid course for pets. (Related: Pet prepping: Emergency treatments you should learn, just in case.)

Medical records

Put together a file of all your pet's health records, medical history, current medications, and supplements. Take care to include relevant information on any chronic conditions your pet might have, as well as the phone number of your pet's veterinarian and the emergency numbers of your local emergency veterinary clinics and shelters.
