Not the best of this series, I think. It's just my impression - which may not be accurate, as I read the Smithsonian Backyard books at distant intervals - but this seems rather less informative than usual. The bulk of the picture book seems to be the squirrel being chased by a cat who is in turn chased by a neighbour's dog. It's all very active, but it lacks the natural detail I've come to expect from the series. The illustrations, though, are gorgeous as always, even if I rather suspect that the cat was the favoured subject of the illustrator!
