Thank you so much for your messages
He's still with me. I'm sorry I didnt post yesterday - I'd spent all night Friday having conversations with myself (LOL!) about what to do, and was shattered yesteray. He'd perked up so much Friday evening and had eaten well, his breathing seemed better. Still, Saturday morning I wanted to see how he was before deciding on the procedure - and again, he was still bright in the morning and looked keen to eat - so at that moment I decided to cancel the appointment, and he did indeed eat well in the morning. It was his day for a diurectic so he had that with his food.
He ate fairly well Sat evening, but he's always a bit 'down' when he has diurectic, so appetite wasnt as good as previously. This morning his appetite not as good and he's not as 'upbeat' as he was yesterday.
I honestly don't think I want to put him through having sedative to be x-rayed - to determine if there is fluid or not (although I think the diurectics have worked somewhat) . I know it could all go well and he'll probably be fine for a few months or longer, but obviously its more risky the weaker he is and I don't feel he's strong enough to survive it - I cannot face losing him through the op. It gives me more time with him, but its not necessarily right for him, its not a cure and will only be temporary.
I believe that the diurectics have probably worsened his kidneys, treatment for one thing, deterimental to another. I don't feel anything needs to be done urgently now, he's sleeping peacefully at the moment, so will see how he goes over the next few days, and when the time comes I'll have the vet come here.
