Cat and seasonal allergies: what to know

Cat allergy is usually triggered by proteins carried in dander, saliva, or skin particles; seasonal allergy is often linked with pollen and changes during particular times of year. Both can inflame the nose and eyes, causing sneezing, itching, watery discharge, congestion, and throat irritation. Some people also develop an itchy rash or asthma symptoms. Symptoms that occur only around cats suggest one pattern, while symptoms that track outdoor exposure or a season suggest another, but more than one trigger can be present. Allergic symptoms do not cause a fever.

Keep a simple symptom diary that records location, contact with cats, outdoor time, and congestion or breathing changes. Wash hands after touching a cat, keep the animal out of the bedroom if possible, and wash bedding regularly. During high-pollen periods, keep windows closed when outdoor levels are high, shower after outdoor activities, and change clothes before bed. A pharmacist or clinician can advise on suitable antihistamines, nasal treatments, or inhalers, especially for children, pregnancy, glaucoma, or other medical conditions. Avoid using someone else’s inhaler.

Arrange a medical review if symptoms disturb sleep, persist despite avoidance, lead to repeated sinus problems, or include a cough or wheeze. Seek emergency help for severe breathlessness, difficulty speaking, blue lips, faintness, or swelling of the lips and tongue. A clinician can assess whether allergic rhinitis, allergic conjunctivitis, asthma, or another problem is involved.

Do my symptoms fit cat allergy, seasonal allergy, or both? Would testing change my treatment? Which nasal or breathing treatments are suitable for me, and what warning signs require urgent help?
