I am sorry for your loss. Here is an email I got. Even though it is about a dog, i think it applies to all pets.
Hope this helps

A Dog's Purpose - from a 6-year-old



I am a veterarian and had been called to examine a very sick ten-year-old Irish Wolfhound named Belker. The dog's owners, Ron and Lisa, and their little boy Shane, were all very attached to Belker, and they were hoping for a miracle.

I examined Belker and found he was dying of cancer. I told the family we couldn't do anything for Belker, and offered to perform a euthanasia procedure for the old dog in their home.

As we made arrangements, Ron and Lisa told me they thought it would be good for son Shane to observe the procedure. They felt he might learn something from the experience.

The next day, I felt the familiar catch in my throat as Belker's family surrounded him. Shane was so calm, petting the old dog for the last time, that I wondered if he understood what was going on.

Within a few minutes, Belker slipped peacefully away. Shane seemed to accept Belker's transition without any difficulty or confusion. We sat together for a while after Belker's death, wondering aloud about the sad fact that animal lives are shorter than humans.



Shane had been listening quietly, piped up, "I know why." His next words stunned me; I'd never heard a more comforting explanation.

He said, "People are born so that they can learn how to live a good life -- like loving everybody all the time and being nice, right?" He continued, "Well, dogs already know how to do that, so they don't have to stay as long."
