So my girl rose is sick with a pretty severe upper respiratory infection. It's worse than I've ever seen any of mine have. The doc put her on baytril and doxycycline to cover it. It's been a week and she sounds tons better but still seems sickly. Today her eye was very red and kind of crusty and she couldn't really open it for a while. Is that normal porphyrin at this point in her treatment course or would it be a bad sign like an eye infection or something?
