If your ferret has a stuffy head or nose...
Turn on a humidifier or boil water on the top of your stove
Turn on your hot water shower and steam up the bathroom then take your
fuzzie in and stay in there for 5 minutes
 
Both these methods work well for us.
 
When the little ones are extremely miserable and stuffy, we give 2-3 drops
of Pediatric Triaminic Cold formula every 6 hours.  Use the medication
sparingly.  Most colds will run their course in a few days.  Make sure
ferrets are eating and drinking plenty of fluids.
 
For upset tummies you can give 1 cc of the syrup from a can of peaches.
Settles the tummies very quickly.
 
Hugs to all. tle
