    Big lump on guinea pig (know what it is?)

    My guinea pig has had this large lump on her far body on the side of her back and we are just wondering what this is, we think it might be a harmless cyst or maybe a tumour. We’ve had her for almost 6 years and she’s never been sick, she’s never seemed to be in pain and hasn’t lost her appetite...

    Weird lump. Tumor?

    I noticed this weird thing in my guinea pigs fur this morning and thought it was just goop in his hair. At closer examination, the skin around it is raised almost like a lump and it seems it split open and now this hard white goop is coming out of it that has dried. Does anyone know what it is?

    Hi forummers! This is my first post here although I have frequently benefitted from the shared knowledge on this site!

    Lump under guinea pig’s nipple.

    I’d been noticing a strange brown liquid coming from Peppa. At this point I hadn’t been sure where it was coming from as there wasn’t anything there that I could tell from. It had only happened twice until tonight it happened again and I decided to look at the source. It was coming from her...

    Weird lump in pelvic area

    So when I picked up my guinea pig, Sabrina, I noticed that she had a weird lump (sort of between her nipples) when I pushed on it, it moved. It was about the size of a penny and very firm.

    Lump Under The Chin

    Hi! Our piggy has a lump the size of a grap. It's located under the jaw, if you imagine sticking your finger through a mans adams apple, that's where the lump is. The vet took xrays of his jaw, because it's very large and not normal, but it was not causing him any pain. The vet did not mention...
