"Rainbow Bridge"

Just this side of heaven is a place called Rainbow Bridge.
When an animal dies that has been especially close to someone here,
the pet goes to "Rainbow Bridge".  
There are meadows and hills for all  of our special friends so they can
run and play together. There is plenty of food, water and sunshine,
 and our friends are warm and comfortable. All the animals
 who had been ill and old are restored to health and vigor. Those who were 
 hurt or maimed are made whole and strong again, just as we remember them 
in our dreams of days and times gone by. The animals are happy and content, 
except for one small thing; they each miss someone very special to them,
 who had to be left behind. 
They all  run and play together, but the day comes when one
 suddenly stops and looks into the distance. His bright eyes are
intent. His eager body quivers. Suddenly he begins to run from 
the group, flying over the green grass,  his legs carrying him 
 faster and faster.
You have been spotted, and when you and your special friend 
finally meet, you cling together in joyous reunion, never 
to be parted again. The happy kisses rain upon your face; your hands
 again caress the beloved head, and you look once more into the trusting 
eyes of your pet, so long gone from your life but never
 absent from your heart.

Then you cross Rainbow Bridge together....
