I'm confused what dry ice has to do with carbon monoxide...they lost me there...

  Dry ice sublimates into CO2 which also suffocates the rats as CO2 is heavier than air and will fill up a burrow, taking away all the oxygen.

    Sure, although the article talks about monoxide…thus my confusion. It’s also a much less pleasant way to go: this is an “as I understand it” to be clear; carbon monoxide binds to your hemoglobin better than oxygen, but your bloodstream doesn’t build up carbon dioxide (which is what causes that panicky “I need a breath” feeling). Adding CO2 accelerates that feeling…
