Same here as for VickiA. I have yet to see a book or pamphlet on piggy care that mentions boar glue, sperm rods, penis hooks - all things my 2 boys have managed to present to me. When each happened for the first time I was in a mad panic wondering what they were & what, if anything, I should do about them. This forum always had the answer.
I've not even seen any mention of the poop eating either - first time I saw one of the boys do it, mad panic again until I researched online. From the enquiries I've seen on this forum about poop eating, I think heaps of new piggy owners get surprised by this!
