The Greenhouse Effect — David P. Reiter

The first in the Project Earthmend Series of environmentally conscious but enjoyable novels for kids who want to learn about how to save the Earth. When Tiger the Cat moves to Canberra with his owner Alexander, there are bound to be a few rough patches in settling in. The dogs next store are anything but friendly, and the nearby park is crawling with snakes and other creatures of the night. But Tiger makes friends with Wanda, the blue-tongued lizard and then finds himself wanting to become a Member of the Sacred Few, a group of magical frogs, actually extra-terrestrials in disguise. This crew has come to Earth on a mission to spread the word about the Great Danger, and the need to heal the planet of pollution and energy waste before it's too late. It's an adventure Tiger can't resist, filled with many surprises along the way. All he needs to do is be sure he won't miss out on his Cat Gourmet dinners along the way...
