I light a candle in rememberance and just try to think that they are in a better place now, someplace where they will never be scared, or cold, or hungry or in pain, and that I know a special little boy is with them and keeping them company.
There is an old tree in my garden where I buried DumDum and Sporty. I don't keep anniversaries of their passing because it is painful to me. So, on the morning of my birthday, I usually go to the old tree and give my greetings remembering the happy times we had. This way is like they are sharing the happy day with me and it is for me a way of telling them I have not forgotten them.
