My guinea pig, he is around 6 years old. Since about yesterday afternoon until now, he is hiding more than usual. He is still eating and drinking, but not as well as he normally does. He seems to be pooping less. I’m concerned something might be wrong.

You have every right to be concerned about Ferb, and I would recommend getting him in to see a veterinarian. Guinea pigs can be very subtle about showing that they don't feel well, and they can go downhill very quickly. Additionally, we worry about things going wrong in older animals, and Ferb is considered a geriatric/old guinea pig. You can find a veterinarian who is comfortable seeing exotic companion animals, such as guinea pigs, on the AEMV website. You can also call around to clinics to find recommendations as well. I hope that this gives you a place to start, and that Ferb feels better very soon!
