Oh dear...this is not good news.Well we heard back from the vet and he does have a mass between his large and small bowel. They believe it may be lymphosarcoma and are recommending exploratory surgery to find out what it is exactly and whether it can be removed.
I'm still in major shock about this, he is our baby. It is nice to see him running around now, it is obvious he feels a whole lot better. But the loss of the stool makes him look quite a bit thinner as well. :-( :-( :-(
