Cats

cats to produce offspring, but to introduce the gene, the hybrid offspring would have to be fertile and be bred back to domestic cats. In 1907, Pocock described the various English domestic cats for Royal Zoological Society and strongly refuted the Pallas cat theory since the skull of Pallas’s cat differed from that of the Angora or Persian of Pocock's time. Modern genetic studies have also shown that the Pallas cat did not contriubte to the gener pool of the modern domestic cat. There are claims that the Persian is descended from the Sand cat (F margarita) based on that fact that both have long hair covering the paws which forms a pad over the soles. Measurements of the length of the hair on the body and feet of both Persians and Sand cats does not uphold this claim. In addition, the long hair on the feet of modern Persians is due to their long coat; in the Sand cat it is a feature since the cats are otherwise shorthaired
