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
