Large white goo coming from my piggys anus

[Luvx]

My piggy is Male, 1 and a few months years old.

I was watching YouTube with him when all of a sudden I see him moving around so I thought he was going to poop so I put him in his cage, but nope.. I see this huge glob of goo, resembling mucus/discharge but more white.

hes had some piggy treats and I noticed it had calcium and threw it away immediately.. is this serious though? I did some research, most says that its him marking his territory

Boars do mark their territory with ‘boar glue’ but maybe he should be checked over with a vet if you’re concerned. Are you weighing him every week ? Is his behaviour as normal ? Is he eating normally and having an 80% hay diet ? That’s very important . Treats are best not given often.Did you mean you threw the treats away ?
Have you only got one guinea pig?

When scent marking you will see your piggy rubbing his bottom along the ground. This may leave a streak of staining on the bedding.
Boar glue is semen. It will dry to be a rock solid lump, and will stick to everything (Ie you can’t get it out of their hair without cutting it off)
Has the discharge happened again?
It’s always best to have anything abnormal or anything you’re not sure about checked by a vet.
