If a cat is lop-eared and a cat is ordinary, what will the kittens be like? - briefly
When a lop-eared cat (a breed with drooping ears, such as the Scottish Fold) mates with an ordinary cat, the offspring can vary in appearance. The kittens may inherit the lop ears, but it is also possible that they will have straight ears, depending on the genetic traits passed down.

When considering the offspring of a lop-eared cat and an ordinary cat, several genetic factors come into play that determine the appearance and characteristics of the kittens. Lop-eared cats, such as those with theScottish Fold gene, have a distinctive physical trait where their ears fold forward and downward. This trait is inherited in an autosomal dominant manner, meaning that only one copy of the gene is needed for the trait to be expressed. However, it is crucial to note that breeding lop-eared cats can lead to significant health issues, particularly osteochondrodysplasia, a condition that affects bone and cartilage development.
The gene responsible for the lop ears is a mutation in the FDD gene, which regulates bone and cartilage growth. When a lop-eared cat is bred with an ordinary cat, the genetic makeup of the kittens will vary. Here are the possible outcomes:
- Heterozygous Kittens: Most likely, the kittens will be heterozygous for the lop-eared gene, meaning they will carry one copy of the mutated gene and one normal gene. These kittens will have folded ears but may not develop the severe health issues associated with the homozygous state.
- Homozygous Kittens: There is a chance that some kittens will inherit two copies of the mutated gene, one from each parent. These kittens will have more pronounced folded ears but are at a higher risk of developing osteochondrodysplasia, which can cause severe lameness and other health problems.
- Normal-Eared Kittens: Some kittens may inherit two normal genes, one from each parent, resulting in ordinary ears and no associated health risks.
It is essential for breeders and pet owners to be aware of these genetic implications. Responsible breeding practices should prioritize the health and well-being of the animals. Breeding lop-eared cats should be approached with caution, and it is often recommended to avoid breeding two lop-eared cats together to prevent the transmission of the homozygous state and the associated health risks. Veterinary consultations and genetic testing can provide valuable insights into the genetic makeup of the cats and help in making informed breeding decisions.
