As cats are familiar and easily kept animals, their physiology has been particularly well studied; it generally resembles that of other carnivorous mammals but displays several unusual features probably attributable to cats' descent from desert-dwelling species. For instance, cats are able to tolerate quite high temperatures: humans generally start to feel uncomfortable when their skin temperature passes about 44.5 °C (112 °F), but cats show no discomfort until their skin reaches around 52 °C (126 °F), and can tolerate temperatures of up to 56 °C (133 °F) if they have access to water.
