If we are allergic to cats but still want to keep one, we can usually take the following measures to reduce allergic reactions:

1) Avoid contact with allergens: First, we need to identify the main allergens, such as cat hair, dander, etc. Once identified, we need to pay more attention later, such as regularly cleaning and changing bed sheets, curtains, and other household items. Additionally, after touching a cat, we should wash our hands immediately and absolutely avoid rubbing our eyes.
2) Choose a hypoallergenic breed: Select cat breeds considered hypoallergenic, such as the common Siberian cat, Bali cat, and Russian Blue cat.
3) Gradual desensitization: If possible, we can start with a small amount of contact with the cat and then gradually increase the contact time to help our bodies gradually adapt.
