If you love Pusheen the Cat, this may be the coloring book for you. You'll get plenty of your favorite kitty here.
The images are not particularly detailed (and so, depending on your tastes, not particularly interesting to color). But you could say that is keeping with the minimalist style of the book's chubby little hero, anyway. Some of the illustrations are quite adorable, just not perhaps what many are accustomed to for an adult coloring book. And the simpler designs may be more suitable for coloring with kids.
So, this is not the most intriguing nor best produced adult coloring book, but you may be happy just to get such a big batch of cuteness all in one place.
