When firefighters rescue kittens or puppies, it’s adorable. When they rescue a mystery rodent, it’s a little more ... um, interesting.

Luckily, no one was hurt and there was no structural damage in the Denver fire. But it's what firefighters found inside that made the story spread like -- well, wildfire.

South Metro Fire tweeted a photo of this very tiny animal, writing that it was “exhausted and covered in soot” in wake of the fire. Firefighters gave it some water and returned it back to the open space.

Their Twitter post had everyone wondering: What exactly was this mystery critter?

South Metro Fire didn’t have an answer, writing “it’s a rodent, but we’re not exactly sure what type.”

One person on Twitter chimed in that it might be a vole or a mole.

Nevertheless, good job firefighters!
