is crap flammable?

Answer 1

Yes and no.

Straight out of the animal – no. It is combustible (after the water is driven out)

Although it can be digested by bacteria to produce methane. And methane is flammable. So yes.


And to add flammable generally means that a substance can catch fire and burn at a temperatures below like 150C (have to check my fire code to give you the exact cut off temperature).

Other fuels like paper and wood are classified as combustible. You have to get the substance hot enough and then it will burn. Actually setters in the great plains of America used buffalo crap to heat their homes.
