And in so doing, the cat was able to mate back to local wildcats, so the population did not have any intense selection mechanism to encourage a symbiotic relationship with humans. Also….
“The Truth about Cats and Dogs
Unlike dogs, which exhibit a huge range of sizes, shapes and temperaments, house cats are relatively homogeneous, differing mostly in the characteristics of their coats.
