The long awaited day has come-Mr Pig has met his three lady pigs. They've been running around the bathroom for a hour and a half and apart from some very loud squeaking and a minor degree of grumpy nipping over a carrot it seems to have gone well. No teeth chattering or obviously aggressive behaviour. They are currently all asleep behind the bathroom door.
I have a silly question-how do I know if they have bonded? Do I just put them in the cage and keep a close eye on them? They don't seem to obviously dislike each other which is definitely good!
