Can you be allergic to cats and not dogs?Updated 7 months ago

es, it is possible to be allergic to cats and not dogs, or vice versa. Allergies are caused by an immune system reaction to substances called allergens, which can be found in a variety of things, including pet dander, pollen, and certain foods. People who are allergic to one type of pet may not necessarily be allergic to another type of pet, as the allergens that trigger their allergies may be different.

In general, people who are allergic to cats may be allergic to a protein called Fel d 1, which is found in a cat's skin cells, fur, and saliva. People who are allergic to dogs may be allergic to a protein called Can f 1, which is found in a dog's skin cells and saliva. However, it is also possible to be allergic to both cats and dogs, or to other types of pets.
