So my daughter has a little piggy, Rue. We got her from a pet store (before we knew better!) about 2 months ago. She had paper bedding and was fine. When we ran out of that, we got the same brand but a different color, and noticed she started sneezing and coughing. She had a slight whistle in her nose. Eyes were good, no nasal discharge. I took her to the vet to get ahead of any potential URI, which the vet confirmed and prescribed antibiotics for 10 days. I also ordered an expensive fleece cage liner. Three days in and she was back to normal, breathing fine, popcorning, etc. But I could NOT deal with the fleece. The only room we have for her is near the dining table in an open concept dining/living room. The smell was unbearable. For $60 I expected better. So after 4 days, I went back to paper. I got kaytee clean and cozy white paper. Two days into that, I went back to the store to get more, and they didnt have the white, they had extreme odor control white and blue. It smelled like it was scented even though it says nothing on the package about scent. Today, 24 hours after using the new "scented unscented" paper she appears to be breathing hard and I can hear her breathing. She is still on antibiotics. She has 2 more days. (5 more doses) and it sounds like we are back where we started. I went to a different pet store and got the plain white kaytee clean and cozy (which doesnt smell). What are the chances that the paper is the cause of her issues? Could it be a new URI if shes still on meds for th4 last one?
