What a hilarious thread and posts. Can relate to randy roos. Went to Cape Hilsborough near Mackay , Queensland a few years ago for wedding anniversary and roos were having "fun" under our cabin, all night. We felt exhausted just hearing them at it. No wonder we have millions of them all over the place.
Hear female porcupines can flatten down their quills to make it "easier" for the male. He wouldn't want to upset her half way thru tho, would he?
