I just looked in on my female bp and noticed that there seemed to be a pinkish film in the water bowl. It was only a small amount but was floating suspended in the water. I just gave her new water only 5 hours ago so I know its not old. She often slithers through her water on her way from one side of the cage to the other. I dont know what it is and have noticed it in the past. She is extremely healthy and eating great. She is 2 and has never had any problems. I have had multiple fecal samples run to check for parasites and all clean. She just urinated as well and all urine was clean and white with no red at all and i have never seen any pink/red stuff on the aspen, its only in the water bowl. I dont know what it could be. Any help would be great. Thanks.
