I'm so sorry for your loss...
You rescued little Clover from terrible living conditions and gave him a glimpse at what a good and proper loving home is.
It really is very saddening that he only got to be with you for a scarce few days, but I'm sure during that time he knew just how much he was loved and how well you took care of him.
You did all you could for Clover, unfortunately he was too weak to recover from years of neglect on his previous home and he is now flying free on rainbow bridge.
Rest in peace, sweet Clover. You were much loved and will be missed.
