I noticed my ladies got really bored while i was spot cleaning. So I got a small piece of cardboard (make sure to round the tips so the piggies don't cut themselves) twisted it and hid some parsley in the cracks. The ladies finished it really quick and enjoyed chewing on it once i was done cleaning! I gave it too my other pigs and some didn't enjoy has much as others, try out with your piggies and tell me if they enjoyed it!
