Cats hear a wider range of sounds than people do, and their advantage is greatest at high frequencies. The exact numbers depend on how the test defined the threshold for “hearing,” so the figures below are only meaningful when they are read alongside their source and test criterion.
How wide is a cat’s hearing range?
Two widely cited sources give slightly different limits for cats. They are not in conflict. They measured hearing under different sound-level criteria, and a range is only comparable to another when the criterion is the same.
| Source | Cat range | Test criterion | Basis |
|---|---|---|---|
| Rickye S. Heffner and Henry E. Heffner, Hearing Research, 1985 | 48 Hz to 85 kHz | Sounds at 70 dB SPL | Behavioral audiograms from two cats |
| Journal of Feline Medicine and Surgery review, 2017 | 45 Hz to 65 kHz (typical range) | Responses below 60 dB SPL | Synthesis of earlier published studies |
The 1985 study put the point plainly: “The hearing range of the cat for sounds of 70 dB SPL extends from 48 Hz to 85 kHz, giving it one of the broadest hearing ranges among mammals.” Because the criterion is a louder 70 dB SPL, the reported range is narrower than it would be at a fainter threshold would suggest for the same animals. The 2017 review uses a quieter 60 dB SPL cutoff and reports a slightly narrower span.
When you quote either figure, state three things: the lower and upper frequency limits, the sound level used to define the limit, and the source. A number without those details is not a like-for-like measurement.

How cats compare with dogs and people
The 2017 review places cats, dogs and humans on the same comparative scale, which makes it the most useful side-by-side reference for general readers. Its authors also caution that the species were not all tested with identical methods, so treat the table as a comparison of published figures rather than a controlled experiment.
| Species | Low-frequency limit | High-frequency limit | Source and criterion |
|---|---|---|---|
| Cat | 45 Hz | 65 kHz | 2017 review; 60 dB SPL criterion |
| Dog | 67 Hz | 45 kHz | 2017 review; methods vary by study |
| Human | 64 Hz | 23 kHz | 2017 review; methods vary by study |
The practical takeaway is that the cat’s advantage is at the top of the scale. A cat can detect sounds in the ultrasonic range where human hearing has ended, which is why high-pitched noises such as rodent squeaks or a toy’s ultrasonic whistle can be audible to a cat and inaudible to a person. Cats are also slightly better than people at the low end on this comparison, but that difference is small next to the high-frequency gap.

A wider range is not the same as better hearing at every pitch or greater sensitivity to quiet sounds. Range describes which frequencies an animal can respond to; sensitivity describes how quiet a sound can be and still be heard. Neither measure in these sources captures how a cat interprets a sound.
How a cat’s ears locate sounds
A cat’s outer ear, or pinna, collects sound and funnels it down the ear canal. Middle- and inner-ear structures then carry the vibration and convert it into nerve signals. The outer ear does more than collect sound, though. It is the part that helps a cat work out where a sound is coming from.

- Each pinna is mobile, and the left and right ears can move independently of each other.
- Turning the ears lets a cat aim its ears toward a sound source before it turns its head.
- Independent movement helps with direction-finding, because a sound reaches each ear slightly differently.
What a wide range does not guarantee
Having an excellent hearing range is a species-level feature. It does not mean that a particular cat hears normally. Several conditions can reduce hearing in an individual animal, and Cornell’s Feline Health Center lists the following as common causes of impaired hearing:
- Congenital defects present from birth
- Infections, including ear infections
- Trauma to the ear or head
- Age-related changes in hearing
Ear disease deserves particular attention. Untreated outer-ear infection, known as otitis externa, can damage tissue over time and may lead to permanent deafness. Cornell’s Feline Health Center also quotes James Flanders, DVM, associate professor of surgery at Cornell University College of Veterinary Medicine: “Most feline ear disorders are readily treatable and will not result in permanent hearing loss.” Early assessment is what makes that outcome likely.

White cats with blue eyes
One specific risk is well documented. According to Dr. Flanders, as quoted by Cornell, about 80 percent of white cats with two blue eyes show signs of deafness at about four days old. Cornell attributes this to cochlear degeneration. The estimate applies to that coat and eye-color group only. It does not mean that all white cats, or cats in general, are deaf or at similar risk.

- Apparent loss of response to sounds, such as no reaction to a familiar voice or a food container
- Persistent head shaking, scratching at the ears, or rubbing the head
- Discharge, odor, redness, swelling or pain around the ear
- Head tilt, loss of balance, or unusual eye movements
Do not start home treatment for a suspected ear problem without a diagnosis. Ear canals differ in how they can be treated, and the wrong product or a damaged eardrum can make the problem worse.
