Cats with wool like sheep? - briefly
Cats do not have wool like sheep. They possess fur that is short and smooth, which helps regulate their body temperature and provides protection. Sheep, on the other hand, have a thick, dense coat of wool that grows continuously and needs to be sheared periodically.
Cats with wool like sheep? - in detail
The phenomenon of cats with wool-like fur, reminiscent of that seen in sheep, is an intriguing subject that has captivated both cat enthusiasts and geneticists alike. This unique trait is primarily associated with the Selkirk Rex breed, which was first discovered in Montana in the early 1980s. The distinctive feature of this breed is their curly or wavy fur, a result of a dominant genetic mutation that affects the hair follicles.
The Selkirk Rex's wool-like coat is not merely an aesthetic novelty but a testament to the diverse variations possible within the feline gene pool. The unique texture of their fur is due to a change in the keratin structure, which leads to the formation of tight curls or waves. This genetic anomaly is similar to that found in some breeds of sheep, such as the Merino, where the wool-producing genes have been selectively bred over generations to enhance fleece quality and quantity.
In cats, the mutation responsible for the Selkirk Rex's distinctive fur has been traced back to a single cat named Miss DePesto, who exhibited this unique trait. Through careful breeding programs, the Selkirk Rex breed was developed, with subsequent generations inheriting and showcasing the same curly or wavy fur. The mutation is dominant, meaning that only one copy of the gene is needed for a cat to display the wool-like coat.
Despite its resemblance to sheep's wool, the Selkirk Rex's fur has several key differences. Unlike sheep's wool, which continues to grow and can be sheared repeatedly throughout a sheep's life, the curly or wavy fur of the Selkirk Rex grows to a certain length and then stops. Additionally, while both sheep's wool and Selkirk Rex fur are made from keratin, the structure and properties of the proteins differ significantly between species.
The genetic mutation that causes the wool-like coat in cats is not limited to the Selkirk Rex breed. Other cat breeds, such as the Cornish Rex and Devon Rex, also exhibit curly or wavy fur due to different genetic mutations. However, the Selkirk Rex's unique trait stands out because of its resemblance to sheep's wool and the fact that it is caused by a dominant gene, making it easier to breed and maintain within the feline population.
In conclusion, cats with wool-like fur are a fascinating example of genetic diversity within the feline species. The Selkirk Rex breed, in particular, showcases how a single genetic mutation can lead to striking variations in coat texture, reminiscent of that seen in sheep. This unique trait not only adds to the beauty and appeal of these cats but also provides valuable insights into the complex world of feline genetics.
