The power just came back on, and something I didn't think about before is my frozen mice/rats. They should be fine, right? I read that freezers stay good for about 48 hours.

All of my thermostats have returned to their original settings, other than the internal clock if it has one. I don't do night drops anyway so I don't really care.

The freezer should be ok for a few hours if unopened. How long food in them stays good depends on whether it's a chest-type or upright, how full it is*, and the outside ambient temperature.

*A full freezer is more efficient than one that is partially full. If your freezer isn't full put some partially-filled bottles of water in it (partially filled so they don't burst) to take up any empty space. If the power does go out it will hold temp longer than if the freezer isn't full.
