I have some Kaytee dust bath that my chinchilla has used twice. The first time was perfectly fine. I mean she did sneeze and rub her nose but over all good. This time, just tonight, she sneezed and rubbed her nose just like before but in the corners of her eyes it was small goo like her eyes had maybe teared and then started to dry up. I don't recall seeing this before she took the dust bath so could it be because of the dust that I have? Is this normal?
