Hi there! So I got my first guinea pig about a week ago. He is a young black abyssinian male. I have a few concerns though. I have noticed the occasional sneezing. Maybe 4 or 5 times a day. And he sounds kind of congested. I am using hay from the petstore. It is Kaytee timothy hay for those who want to know. And his bedding is Kaytee clean and cozy. He is my first guinea pig I ever owned, although I have owned multiple hamsters in the past. His name is Batman for those who are curious. Should I be concerned?
