Measures you can take depend on:
- The ambient temperature and do you need to make your critter's enclosure warmer or cooler. Most of us are worried about our snakes getting too cold, but this time of year those of us with BRB's could be looking at 95*F or higher temps inside our houses if the power goes out. Most snakes would be fine with it, but BRB's and some gecko species that need a narrow temperature range may have issues.
- How many and what kind of critters do you have? Plans for an outage for one ball python will be different than for someone with dozens of snakes ranging from small colubrids to giant pythons.
- Do you own or rent your home? A homeowner can probably use a portable generator (unless it's a condo) or get a whole house generator installed, while someone renting an apartment will have fewer options.
- Do you have somewhere you can take your collection if need be? Again, easier for one snake than a large collection.
