Pete's Pets has the most adorable new kittens in the shop, but are they stolen? When some new kittens go missing from the River Heights Animal Shelter, it's just too suspicious. Nancy Drew and her friends are on the case. Could their archenemy Deirdre Shannon have something to do with this? She's been pining for a pet lately, and the Clue Crew knows she'd go to any length to get what she wants. They need to find the catnapper before any more kittens disappear!
