1. A solar phone charger. Worth it's weight in gold during an extended outage.
2. Battery-powered LED lanterns. They're fantastic when the power goes out. I also keep moon lights (tap lights) to stash around the house, and lots of flashlights. Candles, oil lamps, etc. put out a lot of smoke, and if anyone's prone to breathing problems, it's indoor air pollution (okay for a few hours, but not for extended periods). Not to mention dogs bumping tables and risking a fire.
3. Cloud backup! I've had flash drives fail and lose data. I really prefer storing key documents for evacuation on a cloud-based service now. Putting a flash in a safe deposit box wouldn't be a bad idea, for heirs/executors, in the event one doesn't survive the disaster.
4. Put a repeating entry in your phone calendar to rotate your food stock in the emergency kit! I remember when we last moved, I opened the emergency storage containers and found stuff that was years out of date. Oops.
5. Vetericyn or Puricyn, for humans and dogs.
6. A box of good filtration/respirator masks. In hurricane country, you'll need them when the mold counts go up in the aftermath. In earthquake country, particulates from collapsing buildings can pose problems too.
7. In hurricane country, bug repellent. Mosquito populations explode after hurricanes.
8. I think the air-dried raw (Ziwi, ONP, etc.) and THK is really good stuff to keep in an emergency kit with raw-fed dogs. Stella & Chewies and OC Raw also make dehyrdrated patties that would work. Evacuation may mean living out of a cooler, not being able to find ice, not having a hotel with a fridge/freezer, etc. That's a mess for raw fed dogs that can't eat kibble due to health issues.
6. Shoes & booties. If you live in a city, a major earthquake, tornado or hurricane has the potential to send debris and glass all over. If you have to walk out, you may have to walk through lots of sharp debris. When I lived on the West Coast, I kept a backpack in my car with good walking shoes and socks, in case I had to walk home, if freeways were to collapse. I also had a similar backpack in my office, under my desk. That one had another pair of shoes/socks, a light jacket, plus sunscreen, water and granola bars, since it was a good 10+ miles home.
