Because I believe God accepts our pets into Heaven as they make us happy, I told my girls about the Rainbow Bridge (story is below).
I also told them that our pets that pass always live in our hearts, and in time when we think of them, they will bring smiles to our face. So we talked about things that could help us 'remember' and decided upon a memory garden and that each pet that passes will have a special statue in the garden.
So that's what we started. It began with internet searches for statues that reminded us of our passed pet - a statue that seemed to reflect some part of its personality. I added a St Francis of Assisi to watch over our pets when they're not with us (Wikipedia story at bottom), and the girls chose a rabbit with it's ears perked up for Thumper; since then we've added a cat that's laying in a position similar to Luigi in life.
The garden is outside the front door - which we use every day and the statues face us as we exit the door. And while we waited for the statues to arrive, I planted some shrubs around the 'back' of the garden so when we leave home the little garden looks protected, and the street doesn't see it. This seems to give the memory garden more privacy and makes it more inviting. I've added a bird bath and bird feeder, so there's always animal/bird activity near the statues.
On special days that the children decide on (their birthday, a day in which they've had special memories of that pet, ...)
they go outside and put some special food by the statues for the living creatures - peanuts, corn cobs, sunflower seeds - whatever's in the house they think the creatures would like.
The girls also make sure the statues are clean and go outside with a bucket and soapy water and wash them down. This helps to give them pride in the garden, continues it as theirs, and I think may bring in some nurturing feelings they had for the pets in life.

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, that 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....

Wikipedia: Saint Francis of Assisi (September 26, 1181 or 1182 – October 3, 1226) was a Roman Catholic friar and the founder of the Order of Friars Minor, more commonly known as the Franciscans.
He is known as the patron saint of animals, birds, and the environment, and it is customary for Catholic churches to hold ceremonies honoring animals around his feast day of October 4.
