I think my guinea pig(s) have URIs. They have been coughing about 2x a day sometimes 0x a day. And sneezing a few times a day. This has been going on for about 3 weeks. I bought them HomeoPet Nose relief. Can somebody tell me if they have URI and if they're gonna be ok. Sadly I cant go to the vet because my mom went last time and it was $300. Muffin (3months) sneezes and coughs more than browner (10 months). I feel them hay and lettuce everyday,and they have a nice cage.
