I have 3 female guinea pigs, Cupcake, Chocolate and Cheesecake. I got them all from my local pet store (that was before I discovered how bad it is.) Regardless, I love them all with all my heart, but recently I noticed Chocolate has been sneezing quite a bit. I suspect a URI, but she does not show many signs. I have had them for about 3-4ish months now. I use fleece bedding and would clean/change it everyday. There has also been some reconstruction going on around my house, so it has been quite dusty. Chocolate seems to appear fine, she still eats, popcorn, and chase her cage mates around. I did discover some discharged coming out of her nose. Does anyone else ever had this problem/circumstance? I'm planning on taking her to the vet soon to see what the issue is.
