Hello...after posting a comment about how lovely boars are, I noticed that my older one has a very messy bottom. He had a clump of stools there and I have cleaned it and offered what I cleaned off, to him- he nearly ate the cotton bud too! I wondered if it could be impaction but it was quite soft & he did have some Kale yesterday. I don't want to take any risks so will take him to the vet tomorrow. Does anyone know anything about Ashleigh vet centre in manchester? It is the nearest one to me, and says that it specialises in 'exotics' such as guinea pigs. Also any other advice in the meantime....should I seperate him from his cagemate (who seems to be cuddling a lot closer to him over the last day or two)?
