Catherine - I'm late coming to the very sad news of poor Bill's demise. I understand how you feel and my heart goes out to you. Don't blame yourself - you loved him and gave him a lovely home. I too have heard about these blood clots and it always seems very quick. He was with you when he passed and just think his final sleep was in your arms.
When I lost my beloved Kisi (Siamese) I thought I'd never stop crying - and I did. You will too - but you'll never forget your lovely boy.
I'm away to bed now (it's just past midnight) but you'll be in my thoughts now and for days to come.
Chin up.
Love from Lynne
