Ginger has a big lump on her tummy, near her nipple. So we took her to the vet this evening who found 4 more smaller lumps elsewhere on her body. Sticking a needle in discovered that no they are not abcesses, but are rather more solid than that :(
So the vet took biopsies, but seems to think that getting a proper diagnosis isn't actually going to improve the outcome as there are so many lumps she wouldn't be able to remove them all. The vet gave us some baytril "just in case it helps", and some pain relief because piggies generally don't show pain. She'll get in touch when she gets some results from the biopsies.
It's not looking good for poor ginger :( although she is still quite happy in herself. She's running around, eating happily (beetroot is her favourite so she's getting lots of that now), and pooing as much as ever.
Has anybody got any experience of a guinea pig with lumps? How long till they went downhill? Did they have to be pts? Or did they go peacefully? I don't want to lose her, and her sister will be devastated without her.
