My piggie, Kitten, will every now and again cough like she has a hairball or even sneeze. maybe a couple times a day. She's been on antibiotics a couple of times before (not recently, probably about two months ago) but shes been doing it almost ever since we got her. It's gotten worse lately. (As have mine. LOTS of dust out lately) Could she have allergies? If so what would you reccommend I try? (She's not sick. She only coughs every now and again and very rarely sneezes. Her eyes are as bright as ever, no runny nose) HELP!
