very thin guinea

Question
I have 3 guinea pigs and recently in the last 2 months one of them has been having blood in its urine,this has been treated with an antibiotic but hasnt worked.The GP went into vet for xray and was found to have urine infection and a few stones,which were removed.Two weeks later the GP has lost so much weight it is half the size of its sister.It is eating and drinking fine and seems really happy in itself but is loosing weight so quickly.

Answer
Hi

Weight loss indicates there is still a considerable problem somewhere. It might be something related to the previous infection or it might not.

I realise you have had to visit the vet with your pig a lot recently but a problem like this can only be treated by a qualified professional. If I was there I would examine her and probably be able to tell you what might be wrong but as I am not, please consult a vet.
