I have a friend who is having a weird issue with one of her guinea pigs, and I told her I'd ask for opinions, as this forum is filled with knowledgeable animal lovers
Her one guinea pig is screaming- not their usual happy squeaks. I'm talking seriously high pitched. If she picks him up and holds him, the screaming dies down a lot. He's eating and drinking normally.
She is planning on making a vet visit if it keeps up, but the small animal vet near her is really expensive. If anyone has any idea, it would be fantastic!!
P.S. An idea that has popped up was constipation
