Hello,
Thanks for your reply.
Yes sorry my guinea pig Stitch. Not sure how old he is as I adopted him - but no older than 3 and a half / 4.
He was bleeding out of his privates so I took him to the vets and after several blood tests, scans and x-rays, the vets have now said he has a cyst on his kidney. They are not sure whether it is cancer or an abnormal cyst but it has grown the size of his kidney and they said the only option is to remove it?
But I am really worried about this as it seems a big operation for such a small animal.
Thank you
