Hello! I’m new to guinea pigs so sorry for my lack of knowledge and etiquette. I purchased two young (intact) males for my kids end of November. They were housed together and we’ve had zero issues. Last week one of them seemed to throw up on my daughter (I wasn’t in the room). After doing some research, I have discovered that while they can spit up maybe, they can’t throw up. There has never been any signs in their cage of vomiting. Today it seemed to happen again. My daughter said she didn’t see it come out of their mouths but felt it. It’s rather gelatinous and transparent. They don’t appear to be ill or acting funny, and they are also gaining weight. I’m curious if maybe it’s actually semen instead of vomit? I would post a photo if I could. Does anyone have any ideas? Thank you so much!
