i bought a guinea pig two days ago because my other one needed a friend and i didn’t quarantine the new one at first which i shoukd have done and the new one has been coughing and sneezing so i took them both to the vet and the new one is prescribed antibiotics for a uri but should separate them until she is off or is it too late? they are already bonded but I'm scared that my other one is going to get sick. they are both still babies too.
