Why are hypoallergenic cats hypoallergenic? - briefly
Hypoallergenic cats produce less of the protein Fel d 1, which is the primary allergen in cat saliva and is responsible for triggering allergic reactions in humans. This makes them a better choice for people with cat allergies, as they are less likely to cause symptoms.
Why are hypoallergenic cats hypoallergenic? - in detail
Hypoallergenic cats are often considered less likely to trigger allergic reactions in people with cat allergies. This perception is primarily based on two factors: the type and amount of allergens they produce, and their grooming habits.
Cat allergies are mainly caused by a protein called Fel d 1, which is present in cat saliva, urine, and dander (dead skin cells). When cats groom themselves, they transfer this protein from their saliva to their fur. As the fur sheds, it releases the protein into the environment, where it can be inhaled or come into contact with the skin, triggering allergic reactions.
Hypoallergenic cats are believed to produce less Fel d 1 than non-hypoallergenic breeds. Additionally, some hypoallergenic cat breeds, such as the Sphynx and the Cornish Rex, have shorter or no fur, which reduces the amount of dander they shed. As a result, these cats release fewer allergens into the environment.
Moreover, certain hypoallergenic cat breeds have different grooming habits than non-hypoallergenic breeds. For example, the Balinese and Javanese breeds have lower grooming frequencies, which means they transfer less saliva to their fur. This reduced saliva transfer leads to a decrease in the amount of Fel d 1 on their coat, making them less likely to trigger allergic reactions.
It is essential to note that no cat is completely hypoallergenic. Even breeds considered hypoallergenic can still produce some level of Fel d 1 and may trigger allergic reactions in sensitive individuals. Therefore, it is crucial for people with cat allergies to spend time with a particular cat before deciding to bring it into their home.
In conclusion, the perception of hypoallergenic cats being less likely to cause allergic reactions is based on the reduced production and transfer of Fel d 1 protein due to differences in fur length, grooming habits, and potentially lower allergen production in certain breeds. However, individual responses may vary, and it is always recommended to assess one's specific reaction before committing to a cat.
