Hello all, My 4 year old ferret has been on Bene-Bac for 5 days, after a bout of diarrhea, which cleared up but he is now left with some malabsorption in his poo. He is seeing the vet tomorrow for that. He has no other health problems so far. Yesterday was the first day without Benebac. The day-before yesterday (last day on bene-bac) and yesterday (first day without benebac) he had dark-yellow/orange pee. There was no visible straining (trust me, I watch, VERY carefully) and I couldn't tell if there is any sand in his pee when looking at it with tissues. His belly dips in his urine when he pees on the tile so he always drips around after he pees because it drips off his belly fur when he walks away. There was no frequent peeing and the amount of pee seemed normal to me. He is eating fine, drinking fine, energy level is normal for him. His spleen is enlarged, but we are seeing the vet tomorrow for that too. He refused to pee for me this morning and I had to leave for work, so that is one less datapoint I can give you. When I called the vet today about the orange pee she said that probably it is a side-effect of the Bene-bac, and she doesn't recommend urianalysis. Given that he continued to have the orange pee one day post- bene-bac administration, I am not sure what to think. Did any of you have the same experience? Could the discolored urine be a side-effect of the bene-bac? If so, per your experience, how long does this last? Thank you so much for your help! Sonia [Posted in FML 5952]
