Hi. Basically, yesterday I noticed for the first time that one of my guinea pig's (Pumpkin) nostril (just one I am pretty sure) had this white mucus-looking liquid inside. It would appear in her nostril every time she breathed out, and a little crust of it seemed to be on the outside. I kept an eye on it but today at 1AM i am pretty sure I saw a lot of it hanging out of her nose, but it was dark and hard to tell. She probably wiped it off or it got wiped off when I picked her up cause it is not there anymore. She always sneezes a lot so I am not sure if she's sneezing more than usual, it is hard to tell (but yes she is still sneezing A LOT). I don't know if she is breathing harder than usual or if it is just me being paranoid. Either way, I'm freaked out. Does anyone know what this could be?
