Animal in the chimney
If you hear animals in your chimney or if you smell something coming from your chimney that you suspect is from animals (dead or alive), call your chimney professional. Don't try to remove animals from the chimney yourself. Squirrels, raccoons, and birds often nest in chimneys or accidentally fall into the flue. Since these animals carry a host of diseases ranging from histoplasmosis (a respiratory disease) to rabies, it is critically important that you avoid contact with them.
