Hi,
No words can console a greiving person morning the loss of their fur baby,all you can do is be there for them and listen.
The hole which is left by a loss is so big it seems all consuming,no words,no actions,and no thoughts can make this any better but it does help to have a friend who is there or on the end of the telephone to just listen.Your friend knows that her fur baby is bettter off now, free of pain and running free with all the others at Rainbow Bridge,but that doesnt make the pain go away.
I like most folks on here have suffered loss and it is never pretty nor does it get easier (like some non loving fur baby people say)...time heals a broken heart and memories last forever...
I wish your friend peace.
