This is the story of a young tabby kitten called Boris, and a rather manic Dalmatian puppy called Oliver (or "Ollydog" as Boris likes to call him) and how they are brought into a human home and become friends and get lured into an adventure fighting a Koi carp which seems to have magical, evil powers. Boris tells Oliver that the mischievous fish is trying to enslave animals by stealing their mystical numbers. Boris can be a bit superior in his attitude but soon realises that his dog friend is more clever than he lets on. This is the first in a series of Boriscat books. The next book is entitled "Ollydog and the Battle for Oakdown Forest".
