Why does ultrasound attract cats? - briefly
Ultrasound emits high-frequency sounds that mimic the frequencies of prey or communication in cats, triggering their natural hunting instincts and curiosity.
Why does ultrasound attract cats? - in detail
Ultrasound, which consists of sound waves at frequencies above the human hearing range (typically above 20 kHz), has a unique effect on cats due to their highly sensitive auditory system. Cats possess an extraordinary range of hearing, capable of detecting frequencies up to 65 kHz or higher, far surpassing the capabilities of humans. This heightened sensitivity allows them to perceive sounds that are inaudible to us, including many ultrasonic frequencies. When exposed to ultrasound, cats may exhibit curiosity or attraction because these sounds can mimic the high-pitched noises produced by small prey, such as rodents or birds. In the wild, such sounds are critical for survival, as they signal the presence of potential food sources. Domestic cats retain this instinctual response, even if they are not actively hunting. Additionally, ultrasound devices designed for pets often emit frequencies that are intended to capture a cat’s attention, whether for training, play, or behavioral modification. The novelty of these sounds can also stimulate a cat’s natural curiosity, prompting them to investigate the source. Furthermore, the tonal quality of ultrasound can vary, and certain frequencies may resonate with a cat’s auditory preferences, making the sound more appealing. It is worth noting that not all cats react the same way to ultrasound; individual differences in temperament, age, and hearing sensitivity can influence their response. Some cats may ignore ultrasonic sounds altogether, while others may become highly engaged or even agitated. The interaction between ultrasound and feline behavior underscores the complexity of their sensory capabilities and their evolutionary adaptations as predators.
