In 1988, when Laura Gould brought her newly-adopted cat George to the vet, the vet smirked at hearing the masculine name. He soon turned pale, after taking a closer look at George. George is a calico and he is male. The logic of genetics that resulted from Gregor Mendel's famous experiments with peas tells us that only female cats can be calico. But George and his maleness are undeniable certainties. How do you get a George? This question led Laura Gould on an exploration of the facts and history of genetics. As she dipped into this knowledge, many more questions soon followed.This book portrays Gould's journey through the research and understanding of (cat) genetics and her journey through cat ownership. Ten years after the first publication of ''Cats are Not Peas'', the author updates the tale with two major developments in genetics: the sequencing of genomes and the production of clones. Where are cats on the list of species to first have their genomes sequenced? What was cloned first, a cat or a dog? The answers to these questions - and others - appear in the Addendum included in this new edition.
