The size of the stones in your tank worries me. Those are small enough to be swallowed, but definitely big enough to get stuck. I would seriously consider removing them before she ingests one.

Fridging works like this: Axolotls are poikilothermic (formerly ectothermic, aka cold blooded). Their rate of digestion is tied to how warm they (and their surroundings) are. If you place a poikilothermic animal into a cold habitat, they aren't able to digest as quickly. In order to prevent food from rotting in their digestive tract, they void as much of it as they can. So when you put an axolotl in the fridge, it poops a lot to get all that food out of there. If there is something like a rock in there, the hope is that the force of voiding the gut will also propel out any impaction. It doesn't always work, but if the impaction is small (like gravel), it usually works pretty well. Larger impactions (like large rocks) usually need to be removed with surgery.
