What is this!

[Piggylover123903]

Whenever my Guinea pig goes near my other one he starts vibrating and making a noise and I just noticed this big white clump comes out of his butt it looks solid then he drags his butt across the ground and it goes back in. What is this!

The vibrating is called rumble strutting. It is a normal dominance behaviour. It’s how boars show dominance and how they measure up to each other.

The dragging his bottom along the floor is scent marking. He is using this to mark territory and send messages.

It’s all very normal, don’t worry.
