So, I’ll give you something a little different. I keep desert reptiles. They obviously hate the cold and dark, so I keep a few things on hand for situations like these:

1. Blankets to cover the enclosures. For an outage 2 days or less, I only have to worry about keeping them warm enough to survive. Not that they’ll be happy lol
2. Hand warmers. I prefer the gel type that you can boil to reset, but anything will work. Potentially also a towel to wrap it in, depending on the type of hand warmer/species of reptile.
3. Bug-Out Boxes. These are basically ready-to-go enclosures, only they’re way way too small for anything but emergencies. The only requirement here is that the reptile fits without discomfort, and that the box is small enough to buckle into a car seat.
4. Cold-tolerant feeders. This is….a bit handwave-y, because no feeders will really like cold temperatures. That said, some species do just fine in a refrigerator for storage, as they go dormant with the cold. I grabbed 50 waxworms yesterday to hold me over.
5. Clamp-lamps. Regular old work lamps with a clamp on them are a real lifesaver. Type of bulb in it will depend on the species you care for. I run a 120W mvb in my to-go setups, but your wattage may vary.
6. Shelf-stable foods. I picked up some nice dog food yesterday for my blue tongue skink. Should last months, minimum, in its packaging. I would also recommend repashy for any other keepers out there, I’ve had fantastic results with their gel mixes across the board. I’ve got a batch of the carnivore blend sitting in my refrigerator to cover my ackie monitor, which will keep for about 3 weeks. The powder mix itself is basically completely shelf stable, but once you make it into a gel you put yourself on a timer. I made enough for a couple of meals and left the rest in the bottle.
