I'm completely stumped as to what could be wrong with my guinea pig Clover. She is eating, drinking, pooing and peeing completely normally. I've taken her to the vet and they said that her breathing sounds fine, she is slightly (.13 grams I believe she said) overweight, and otherwise is fine. But she is sneezing, wiping her nose, sounds like she her nose is stuffed up, trembling which she has never done before when I hold her, and making a noise that is hard to explain. Almost like a bunch of mini pops when she breathes in and out. I could include a video if anyone here would like a listen, though it's hard to capture. I'm just wondering what anyone else makes of this? The vet said that they don't think she needed an xray or medicine, and it's just allergies. I'm really starting to doubt that. Any response is greatly appreciated!!
