Why is my guinea pig whining and chattering teeth when I touch him?

Updated On September 23rd, 2025

Pet's info: Small Animal | Unknown - Small Animal | Male | 6 months and 9 days old

Hi my guinea pig is having an issue. He seems to be in pain when I pet him. At first, it was just whining but now it’s teeth chattering and backing up. I normally handle him well and he loves laptime. His cage mate doesn’t do this. So their both under a year and I’m concerned my guinea pig has mites. Plz help!

Hello, and thank you for your question. I'm very sorry to hear that Marshall is unwell. If he is lethargic, not eating well, cried when you pet him, or is teeth chattering, I would be worried he is in pain. Possible sources of pain include intestinal bloat, dental pain, scurvy, or infection. I would highly recommend getting him seem by a vet within the next 24 hours, preferably one that has experience dealing with guinea pigs. They can help to determine the source of Marshall's pain, and offer supportive medication such as fluid therapy and pain medications, and antibiotics if necessary. In the meantime, try to minimize stress by not handling him too much, and provide easy access to his food and water. If he is not eating well, try offering more of the fresh veggies that he typically enjoys. Make sure you are feeding both pigs plenty of vitamin C which will help prevent scurvy. Oranges, green peppers and pellets fortified with vitamin C are all good choices. I hope this helps, and that Marshall is feeling better soon!
