so- i was looking at Vegas when i noticed that his whole chin is covered in like a dry yellow colored "substance".i dont even know what. i smelled it quickly to see if maybe he was laying in pee or something-but it did not smell at all like urine, it really didnt have a smell. i was thinking maybe he got dirty when he was laying in his litter box or something-but im just not sure.. i heard that sometimes the scent glands under the rabbits' chins could sometimes get blocked..maybe this is what happened-for now i am going to brush it out and loosen up the fur there-and see what happens..but if anyone has any ideas-please tell me. holland lop male-around 20-22 weeks old. lives indoors. hasnt been fed anything unusual or different. feed- pellets, 1 large carrot a week with a small amount of parsley. has been using the litter box like normal:: everything is the same besides the issue under the chin..
