What is a baby echidna called?
Um, how exactly do porcupines reproduce?
It seems a little dangerous…
Female porcupines (porcupettes) are only fertile 8-12 hours a YEAR!
Males will fight over females and get stuck with quills. If you see a pile of quills in the woods, it’s probably from a porcupine fight.
If she likes the male, she will flip up her tail where there are no quills and he can mate with her (very carefully).
The don’t shoot out quills, but they do have 30,000 of them and they grow back in about a month.
Porcupines are the 3rd largest rodent in the world.
They LOVE salt. They will chew on anything that has the slightest amount of salt on it, like the wheelbarrow handle you were touching.

Mouse- 1 year
Dog/Cat- 3 years
Horse- 4 years
Elephant- 30 years
Tiger- 9 years
Tick- 2 years
