What will happen if you breed a Scottish Fold cat with another Scottish Fold cat? - briefly
Breeding a Scottish Fold cat with another Scottish Fold cat can result in kittens that inherit the distinctive folded ear trait. However, this practice is discouraged due to potential health issues associated with the gene responsible for the ear shape.

Breeding two Scottish Fold cats can lead to several outcomes, primarily due to the genetic basis of their distinctive ear characteristics. The Scottish Fold's unique ear shape is the result of a dominant gene mutation that causes the cartilage in the ears to fold forward and downward. When breeding two Scottish Folds, it is essential to consider the potential genetic consequences and health implications for the offspring.
Firstly, it is crucial to understand the genetics involved. The ear-folding trait is caused by a mutation in the fibroblast growth factor 3 (FGF3) gene. This mutation is dominant, meaning that if one parent carries the gene, there is a high probability that the offspring will inherit it as well. When two Scottish Folds are bred together, all the kittens will inherit at least one copy of the FGF3 gene from each parent.
In terms of phenotypic outcomes, there are a few possibilities:
- Homozygous Dominant (FF): If both parents are homozygous dominant for the trait, meaning they have two copies of the FGF3 mutation, all their offspring will also be homozygous dominant and exhibit the folded ear phenotype.
- Heterozygous (Ff): If one or both parents are heterozygous, carrying one copy of the mutated gene and one normal gene, some of the offspring may inherit two copies of the normal gene (ff), resulting in kittens with straight ears.
- Health Implications: Breeding Scottish Folds together can also exacerbate health issues associated with the breed. These include osteochondrodysplasia, a condition that affects bone and cartilage development, leading to abnormalities such as shortened limbs and tails. Additionally, intervertebral disc disease is more common in Scottish Folds due to their genetic predisposition.
To mitigate these health risks, many breeders cross Scottish Folds with American Shorthairs or other non-folded ear breeds. This practice aims to produce cats with the desired folded ear appearance while reducing the likelihood of severe genetic disorders. However, breeding two Scottish Fold cats without considering the potential consequences can result in a higher incidence of health problems among the offspring.
In conclusion, while breeding two Scottish Folds may result in kittens with the distinctive folded ears, it also carries significant risks for the offspring's health and well-being. Responsible breeding practices should prioritize the genetic diversity and overall health of the cats involved to ensure the long-term welfare of the breed.
