Cats vs. robots : This is war
(Book)

The Robot Federation and the Feline Empire have been at war for eons. And now that fight is coming to a tiny primitive planetoid...Earth. The mission for both cats and robots: retrieve the Singularity Chip. With it, cats can live past their nine lives, and robots are granted eternal battery life. Meanwhile, twin siblings Max and Min Wengrod are as different as can be. Min always gets good grades, and she loves to read and build robots. Max hates school, and prefers to play games and spend time online with friends. When Max rescues two kittens and is determined to keep them, Min is horrified that these furballs could ruin her chances at the Battle of the Bots competition. But with hidden forces at play in their own house, and the larger war between cats and robots fast approaching, will the twins be able to put aside their differences before they get caught in the crossfire? -- from Amazon.
