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 defence force in the universe!
In the fourth book in the series the Spacemutts are joined by Monty, a posh poodle who is far too snooty for saving the world. But when Lady Fluffkins launches her ultimate weapon of mass destruction, it's Monty who must save the day . . .
