Does Pidgey evolve into maltress if you use a firestone?

That's not quite right! Pidgey doesn't evolve into a "Maltress".

Here's what's likely happening:

* You might be thinking of "Maltress" as a misspelling of "Pidgeot". Pidgeot is the final evolution of Pidgey.

* Fire Stones are used to evolve some Pokemon, but not Pidgey. Pidgey evolves into Pidgeotto at level 18, and then into Pidgeot at level 36.
