hello guys,
my new hamster(3 months) and his brothers cough too much.
Their cough began a long time ago. (maybe 1month)
They hardly cough when they are sleeping and running.
The symptoms are the same for him and his brothers.
we had go to many vets(more than 6), but even they don't know reason...
vets said it's not cold, flu, and allergies.
so I need your help
Is this an inherited disease???
if you had some situation like this, or have some advise, please tell me.
thank you.
