Hello, my name is Conner. I just adopted a female guinea pig and we named her Sweet Pete. I think she's about 1-2 months old. She seems healthy and loves to be held. She loves fruits and veggies, hay, etc. Her bowel movements are normal. But one thing I noticed is that she had a little bit of crust around her nose. I got a little worried and did some research online and I didn't find anything but extreme cases of URI. She "wheeks" and has no other signs of a sickness (hair, eyes, etc.). She no longer has the crust around her nose but it seems like if you tell someone online that your guinea pig isn't flawless than they have URI (and I completely understand why they need good vets and immediate attention). Please let me know if your guinea pig has ever has a slightly crusty nose and sneezes maybe 5-10 times a day. Keep in mind that she's a baby and does not have a runny nose or eyes. She seems REALLY happy too. I'm kind of paranoid due to all of the answers I read on many forums. Anyway, thanks for taking the time to read this!
