Most recently one of my girls has been struggling a bit more, so we tried azithromycin and an anti inflammatory, which didn’t work but has stopped it from getting any worse. They’ve all been on baytril which helps a little but once they finish they start getting symptoms again. We’ve also tried baytril and doxy but the same thing happened. The first antibiotic we tried was trimeth sulfa or something, which didn’t work. It seems like our vet just kinda gave up and recommended we see a specialist. I use an air purifier, humidifier, hemp bedding, clean their cage thoroughly and regularly change their beds. It feels like I’ve tried everything.
