Satchmo is sick!!!!!!!!

I'm just in a dither here.  I can hardly think.  My Satchmo has been losing weight and recently he almost got out of his harness because it was too loose.  I took him to the vet yesterday and had labs done.  The vet called me and said she had never seen liver function tests with such high results in her entire career and neither had any of the other vets in the practice.  His GGT was 20,000 times normal!    I really don't understand.  He eats and drinks well, he pees and poops normally, he plays with Austen and chases the cats.  He was just losing weight.

So, today he went back for an abdominal ultrasound to see what the deal is.  She just called me to say that Satchmo has a very large mass on his liver and she wanted to do an xray to rule out metastatic lesions to his lungs.  I, of course, said yes. 

She called back to say there is a spot on his xray but she doesn't think it is a lesion.  So I got him home now, but tomorrow he and I will be going to a specialist to see if he is a candidate for surgery.  I'm a basket case!
This is my little man!  I cannot seem to get my head around this. 

I'll try to remember to update tomorrow after speaking with the specialist----if I can.
