LES here. I don't know how I missed this whole thread, but I am just seeing it tonight. What an ordeal Alex has been through, but how fortunate for sweet Alex to know love and compainionship in his final days. You are such a kind person to have done all that you have for him.
Godspeed to the RB little Alex. Once there, may you be whole again, and run and play and have no pain. May you see once again.
RIP little one, RIP.
