Take it to a vet.
I think
nothing i dont think. she/he just pees alot
No it depends if it has blood in its wee if it has it probably has got a kindey problem if not its what your feeding it foods like celery make them pee alot more than usual
when he pees on the carpet or you or the towel then tap him and tell him no but i would keep him on a towel if i were you. but if they do then put them back in the cage.
Just like human kidneys, guinea pig kidneys filter the blood to maintain health.
I would worry if you lift a guinea-pig by the tail. Guinea-pigs do not have tails so nothing will happen. You must mean something else.
pooping blood
=yes of cource==the blood helps the guinea pig push out the sacks with the babies inside=
When my guinea pig need to pee, she starts nibbling on my clothes if I'm holding her. If that doesn't work, she backs up, and pees on my lap, yuck! When she is in her cage, she goes to a corner, and puts her butt up, and pees. When my guinea pig needs to pee, he starts saying bad words
What I would do is take the guinea pig to the nearest Vet or Animal Doctor as any bleeding is serious
If your guinea pig is that cold, that is definitely not a good sign. The temperature should be about 64oF - 72oF. No lower or higher. Or if your guinea pig is not moving either, it could have passed away. When an animal dies, the blood stops moving, therefore the blood temperature severely drops.
Trauma to a guinea pig's eye can cause a condition called hyphema, where blood leaks into the eye's anterior chamber. This can make the eye appear white or milky due to the presence of blood. It is important to seek veterinary care if you notice this symptom in your guinea pig.
