Splat the Cat: what was that?

Today's countdown to Halloween reading suggestion: Splat the Cat: What Was That? Because sometimes even for an horror aficionado like myself, you just need to share a moment of literature with your young son and you can't go too scary. (Well, I think I could, but my wife would not be happy.) So anyway, this is one Wolfie quite likes. Splat the cat must find his mouse friend Spencer in what may or may not be a haunted house. On Halloween night. After trick or treat. It's kind of cute and in the end the ghosts are just the product of their imagination. Or are they?
