Which pet animals hear ultrasounds exceptionally well? Cats! Cats are nocturnal predators and therefore have excellent hearing, among the best of any mammal. They can detect an extremely broad range of frequencies, ranging from 55 Hz to 79 kHz. This is far more than humans (31 Hz - 18 kHz), and dogs (67 Hz - 44 kHz). Cats ability to hear ultrasound is probably important in hunting, since many species of rodents make ultrasonic calls.
