Judging from the title of this you might think I have done no research but that is not the case. I tried to hold one of my male guinea pigs (all male) and I noticed a small piece of hay coming out of his bladder. I am very concerned because I was able to carefully remove it without my guinea pig being in discomfort. But he has other nasal issues as well in the few weeks thet I have had him. I don’t know if he is getting over a cold and happened to walk over some hay or if he is actually hurt. Please help.
