Female rats wiggle their ears when they are in heat, to excite male rats and encourage them to mate. [4] Ear wiggling was a shtick in Hal Roach comedies such as Laurel and Hardy and Our Gang. To achieve this effect, performers such as Stan Laurel would have their ears pulled by threads which would not be visible in the film. [5]
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]
Cat genetics describes the study of inheritance as it occurs in domestic cats. In feline husbandry it can predict established traits ( phenotypes ) of the offspring of particular crosses. In medical genetics , cat models are occasionally used to discover the function of homologous human disease genes.

[15] [16] Examples of these genetic mutations and physical abnormalities are dwarfism, the lack of protecting fur in hairless cats, and fold-eared cats. Furthermore, several countries or states have prohibited breeding with certain of the genetic mutations in cats, including Scotland , [ 17 ] [ 18 ] Victoria and the Australian Capital Territory ...
These genes affect embryogenesis and can confer tameness, smaller jaws, floppy ears, and diminished craniofacial development, which distinguish domesticated dogs from wolves and are considered to reflect domestication syndrome. The study concluded that during early dog domestication, the initial selection was for behavior.
An abundance of accessible sources that incorporate breed identification panels can be utilized for personal use by breeders and owners to determine the genetic workup of a domesticated cat. Due to the highly known genetic distinction within the Felidae family, "this international cat parentage and identification panel has a power of exclusion ...
The large ears, eyes, and many vibrissae (whiskers) of the cat adapt it for low-light predation. Cat senses are adaptations that allow cats to be highly efficient predators. Cats are good at detecting movement in low light, have an acute sense of hearing and smell, and their sense of touch is enhanced by long whiskers that protrude from their ...
