Once again, Bidner has created a delightful study that presents scientific information in a fun and accessible way. Children will enjoy learning how their cuddly domesticated kitties evolved from bigger, more ferocious cats, and what traits they still have in common with lions, tigers, panthers, and the rest of the feline family. Everything about the book is appealing, from the attractive self-contained spreads to the captions, bold headers, and blurbs that communicate concepts quickly.
