The deal was concluded by Harriet Wilson, editorial director of HarperCollins Children's Books, and Rosemary Canter of United Agents.
Author Ian Whybrow's title will be published in March 2011 and is intended for both boys and girls aged seven and over.
Wilson commented: "A funny and heart-warming meerkat story from Ian Whybrow? It doesn't get much better than that. Ian has an incredible ear for voices and ever-popular meerkats are the perfect subjects for his talents.
"He has created an unforgettable cast of characters who boys and girls will fall in love with. Meerkat Madness is an editor's gift and is sure to be a hit for spring."
