What would you do if you lost a pet? Where would you go if you found one? At the Rainbow Street Shelter a cockatoo will greet you and a little round dog will make you welcome. Meet Bear the border collie, Buster the marmalade cat, and Bessy the goat, as well as rabbits and guinea pigs and mice. There's even a pony called Pebbles, and the children who become the animals' friends. But where does a lion cub fit in?
