Just wanted to let everyone know that I took my little guy to the vet. A urinalysis was done along with a usual physical with palpation. Both were normal- no crystals found in the urine, no sign of bacteria, no lumps found on palpation (He's a good vet and I know he was thorough). A fecal was also done and lo and behold - he has giardia. So now he and the rest of my business have to take Flagyl since they all share the same cage and litter boxes. I have no idea where the giardia came from but giardia is spread oral-fecal or through fecal contaminated food or water. Remember, I recently adopted this little guy - who knows how long he has had it. Does anyone have more info on giardia? My "Ferrets for Dummies" had a very brief page on it. The Flagyl dose prescribed is .10 cc twice a day for 10 days. When I dosed everyone today, they almost vomitted! The gagging was horrible- does anyone know of a more palatable way to dose them? I know that giardia can be spread to humans also. Anyway, the bladder mystery was not solved, but the vet said that sometimes an infection can be there even though tests are negative. But the Flagyl will work on that infection at the same time if there is any infection, per my vet. Thanks to all again. [CY] [Posted in FML issue 4492]
