Jealousy.

[monalipschitz]

My two boars have been living together happily for 3 months but recently I've noticed the occassional altercation with one rumbling a little and charging at the other, the the situation reversing. It's been back forth between the two with my Gretz having a go at mum's Dan when I talk to Dan and Dan charging at Gretz when mum talks to Gretz. It must be jealousy. They're the best of friends as long as we humans keep to our places

Do piggies often to attach to their human like this?
