Hello. I am replying to the one on the healthcare section as it seems more appropriate
. Maybe one of the mods will come along and remove the duplicate post.
So sorry to hear your hammy has a respiratory infection. How old is she? Antibiotics are the way to go so fingers crossed. Is it baytril? They hate the taste of that. Some people suck up runny honey in the syringe with the baytril to make it more palatable. It’s quite important they get the full dose each day and finish the course.
Other causes, other than a bacterial infection, could be allergy or a viral infection. Has anything changed in her environment recently? Change of bedding eg. If it’s viral it should clear up on its own. Hamsters can actually catch colds from humans.
