He's gone, he was so poorly, vet could have done the x rays and drained, if there was fluid, but his heart sounded so bad, she thought the sedation would have pushed him ove r the ege anyway - plus if he survived the procedure, ultimately as his heart was so bad it most likely wouldnt have given him much more time anyway, so made the decision, was my vet this time and she had a cat with HCM who went downhill suddenly like this too. They were so lovely, let me sit with him on my lap for a while before he was pts, he went to sleep so quickly and gently, I realy wanted him to be at home for this, but was best to do it there and then I suppose, heartbroken
