I am so sorry for your loss.
Liver shunt can be a scarey disease. His poor little body was very sick before the surgery and he was just so small. You are a great Momma and you took care of him the best that you could. You saw him very sick and just wanted him to get better, I know you love him dearly and trust me, he knows too and he loves you back very much. God has plans for all of us, including our precious furbabies. I know the pain and the guilt and the heart hurt you are feeling right now seems like it will never end, but you will one day find peace, your memories and your love will put a smile on your face soon. And maybe one day when you feel the time is right, you can open your heart and home to another furbaby....Again, I am so very sorry
