Have tried to put up a link to the article but it has been taken down - a lady in lower North Island caught ten stoats in one trap in one day. She was mucking around with the horses and saw a stoat so set a "trapinator trap". A while later while walking past noticed she had one so went to empty the trap and another ran out of the trap, it had been eating the caught one. Soon after she went past and noticed she had caught another and it was also half eaten. Eventually over the course of the day she had caught ten, she did say that one was bigger than the rest [it was hard to tell from the photo] so maybe a mum with a large litter. They may have been hungry as mum may have been struggling to feed such a large litter but it does prove that stoats will eat stoats, even there mum?, so i guess they would eat weasels under some circumstances which kinda answers the question i had asked earlier on.
