Read, many of the diseases that occur in American Shorthair cats are due to inbreeding, which is often done to maintain a certain look or characteristic. Inbreeding can cause a reduction in genetic variation, which can then lead to increased susceptibility to different diseases and disorders, a phenomenon known as inbreeding depression.
Inbreeding depression has been linked to a reduced lifespan in American Shorthair cats. A lack of genetic diversity can lead to increased rates of inherited genetic diseases such as polycystic kidney disease and hypertrophic cardiomyopathy. These diseases can become more common if breeding is done within a small gene pool with limited variations.
Below is a table showing some of the common diseases found in American Shorthair cats that can lead to reduced lifespan:
| Disease Name | Description |
|---|---|
| Feline Lower Urinary Tract Diseases (FLUTD) | A group of disorders that affect the bladder and urethra, leading to difficulty urinating and extreme discomfort. |
| Polycystic Kidney Disease (PKD) | A hereditary disease causing fluid-filled cysts to develop in the kidneys, ultimately leading to kidney failure and death. |
| Hypertrophic Cardiomyopathy (HCM) | A thickening of the heart’s walls, making it harder for the heart to efficiently pump blood. |
| Progressive Retinal Atrophy (PRA) | Progressive loss of vision due to the degeneration of photoreceptor cells in the eye. |
Although there is a clear negative impact on the lifespan of American Shorthair cats with a lack of genetic diversity, there is a solution: increasing genetic diversity through selective breeding or outcrossing. By introducing new genetics into a breeding program, breeders and owners can reduce the likelihood of inherited genetic diseases and increase the lifespan of American Shorthair cats.
