RattyRat's Review: This is one of the first antibiotics you want to try when your rat is starting to show signs of respiratory infections, the main indicator being noisy breathing (sounds like the rat is talking), but can also include red tears around the eyes/nose, sneezing, and in much more serious cases labored breathing. You will need "Rat Health Care" by Debbie Ducommun reviewed in the Book section of this site to administer this medicine.
