Hello everyone! Not too long ago, I had 3 female ratties. My one girlie was 4 years old, and had a ton of red liquid coming out of her nose, and ocassionally had red eye crusty's. She was very congested and it scared me. I talked to my friend who works at a pet hospital and he gave me a medication to help her. He told me to give it to the other 2 as well, but in a smaller dose. I forget what the medication is called. Unfortunately, my girlie passed away about a week ago. I have continued to give the two younger ones the medication. Today, I got a new girlie. I was concerned about if I should give her the medication even if she wasn't around the sick girl at all. But she has been around the other two girls. Should I begin giving her a small dose, or should she be fine?
