Preparing for emergencies?

[Bogertophis]

When you say hand warmers, do you mean the air activated ones, or the ones that you snap and chemically activate that are reusable? I'm setting up an emergency box right now and all of the reusable ones seem super expensive ($20 for 2)!

Really that's up to you...but I keep on hand the disposable single-use kind. Re-usable @ 2 for $20 doesn't sound expensive to me... Not for saving my pet's lives.
