“At long last,” George M. Eberhart begins his lengthy review of Karl Shuker’s Mystery Cats of the World Revisited: Blue Tigers, King Cheetahs, Black Cougars, Spotted Lions, and More in the Summer 2021 issue of the Journal of Scientific Exploration. “After 31 years, the first book by noted British zoologist and cryptozoologist Karl Shuker has been expanded and updated. Mystery Cats of the World  first appeared in 1989 and was the only book to review feline cryptids worldwide. In this 2020 edition, Shuker repeats this admirable achievement, and in the process gives us a solid overview of current knowledge of felid evolution, taxonomy, and genetic variation. In fact, the only feline mystery cat he does not describe is Hello Kitty. This edition will leave you purring with cryptozoological delight.”

How is it possible to improve on the only indisputably definitive work on mystery cats in existence? Well, Karl Shuker has done just that. His very first book, Mystery Cats of the World, is a classic of the cryptozoological literature that’s now highly sought after by collectors and lauded by cryptozoologists and mainstream zoologists alike for its scrupulously scientific, objective analyses. Now, after more than 30 years, Shuker has delivered Mystery Cats of the World Revisited: Blue Tigers, King Cheetahs, Black Cougars, Spotted Lions, and More, a fully illustrated, updated, greatly-expanded edition of that original work that examines many new mystery cats reports as well as revisits those previously featured in the original 1989 edition. This beautiful new book is more than 400 large-format pages long with more than 80 illustrations and weighs a hefty 1.5 pounds. So just what are these enigmatic cat-like animals that have been glimpsed in wild and lonely areas of the world?
