Cats have one of the broadest ranges of hearing among mammals. [11] Humans and cats have a similar range of hearing on the low end of the scale, but cats can hear much higher-pitched sounds, up to 64 kHz, which is 1.6 octaves above the range of a human, and 1 octave above the range of a dog.
Deafness can occur in white cats with yellow, green or blue irises, although it is mostly likely in white cats with blue irises. [4] In white cats with one blue eye and one eye of a different color (odd-eyed cats), deafness is more likely to affect the ear on the blue-eyed side. [1] Approximately 50% of white cats have one or two blue eyes. [5]
The damage can become permanent (permanent threshold shift, PTS) if sufficient recovery time is not allowed before continued sound exposure. [1] When the hearing loss is rooted from a traumatic occurrence, it may be classified as noise-induced hearing loss, or NIHL. There are two main types of auditory fatigue, short-term and long-term.

Hearing aids are devices that sit in the ear and amplify sound, which helps with age-induced partial hair cell loss. [10] Cochlear implants are a more invasive treatment that bypass the hair cells completely by sending electrical signals from the environment straight to the auditory nerve fibers . [ 11 ]
The team surveyed over 400 cat owners who had lost another pet in the past and asked them questions about any changes in their cat's short-term and long-term behavior after the loss.
After surveying more than 400 cat owners about their pets' behavior after another cat or dog died, the study determined that cats showed behaviors that are typically associated with grief ...
Fel d 1 is the most prominent cat allergen, accounting for 96% of human cat allergies. [4] The remaining cat allergens are Fel d 2–8, [5] with Fel d 4, a major urinary protein found in the saliva of cats, [6] occurring the most in humans among the other seven allergens. All cats produce Fel d 1, including hypoallergenic cats.
They surveyed over 400 cat parents about their cats’ behavior after losing another cat or dog, and found that they showed behaviors we tend to associate with grief, like eating less and playing ...
