🐱 Cat allergies are the most common pet allergy in children. While asthma isn’t always caused by allergies, about 90% of children with asthma also have allergies, and up to 40% may have asthma symptoms triggered by cat exposure.
👉Why do cats cause allergies?
Cat allergens are proteins found in dander (skin flakes), saliva, and urine. These tiny particles travel easily through the air and stick to furniture, clothing, and surfaces, making them very hard to avoid. When sensitive children inhale them, symptoms may include sneezing, itchy or watery eyes, a runny nose, hives, coughing, wheezing, or shortness of breath.
👉How do I know if my child is allergic?
If symptoms show up around cats, an allergy may be the cause. The most accurate way to determine this is through allergy testing, which can be performed using either a skin test or a blood test.
👉Are there hypoallergenic cats?
Unfortunately, no. All cats produce allergens.
👉Can allergen exposure be reduced at home?
Some strategies may help a little, though they’re often not fully effective:
✅Keep cats out of your child’s bedroom
✅Use HEPA filters, vacuum, and clean frequently
✅Wash hands after touching the cat
✅Keep litter boxes clean (by someone without allergies)
👉Treatment options
Medications like antihistamines or nasal sprays may help. In some cases, allergists may recommend allergy shots, though they don’t work for everyone. Children with asthma and cat allergies often need stronger asthma control if a cat remains in the home.
👉Important to remember
If your child already has asthma and a confirmed cat allergy, living with a cat will likely worsen symptoms. Families considering a pet may want to explore fostering first. Keep in mind that cat allergens can linger in a home for months.
If you’re concerned about allergies or asthma triggers, talk with your child’s pediatrician or an allergist for guidance tailored to your family. 💜
