Q: What is the lineage of cats?

The other lineage appeared in Egypt between 6,400 and 1,000 years ago before spreading throughout the Mediterranean. Both lineages continued to breed with the African wildcat during their respective dispersals.

Q: How big is a full-grown cat?

The average weight of a household cat varies from 2.7 to 4.5 kg (6 to 10 pounds), although among non-pedigreed cats weights up to 12.7 kg (28 pounds) are not uncommon. Average lengths are 71.1 cm (28 inches) for males and 50.8 cm (20 inches) for females.
