Did you know that there are Aliens living among us? You might have seen them around - they've got fur, whiskers, and a fondess for mice . . .
That's right, cats: a whole army of mean old moggies hell-bent on world domination. But don't worry; Earth's not going to give up without a fight. This little blue planet happens to have the best interplanetary canine defense force in the universe!
In this second action-packed adventure, the evil empress Lady Fluffkins launches a fleet of deadly flying saucers from Mars, and it's up to the courageous Spacemutts to save the day. Scamp, the newest recruit, becomes a hero as he defeats the Martian Moggies with a Cat Litter Cannon.
