How many have had this happen.. I go in the snake/rat room and smell that horrible smell.. I first check all the rat tubs. Then I check all 14 tubs again. Nothing. Then I check all 30 something snake tubs. Nothing. Now I begin to wonder if a rat escaped and died under something. I'm looking under everything with a flashlight. Where the heck is it?!? I check the rat tubs one last time sniffing each one trying to pin point it. I finally find it completely buried under the bedding. An older male that I should have cycled out long ago but man was it an ordeal trying to find it. So if you have a lot of rat racks and you walk in there one day and smell that awful smell, start digging if you can't find it!
