I noticed a few days ago that my white bunny tinks had some yellow staining around her bottom area, shes always been a very clean bunny and i assumed it was my fault for being slightly lapse on changing the litter tray everyday, so i gave her bottom a brush out and did the littler tray. However today she has got another wet bottom she lives with my other three and they don't have it. I just gave her bottom area a brush and 2 big areas like 50p pieces the fur just came out and left big bald patches! Ive looked through her fur and she definitley has mites or fleas I feel terrible, going to take her to the vets but does anyone have any ideas? I am very worried.
