Cat Allergy in Humans Market Size, Share, Growth, Trends, and Global Industry Analysis: By Product Type (Symptom Relief Drug and Allergen Blocker, Air Purifier, Allergen Immunotherapy, Others), By Application (Allergy Treatment, Allergy Prevention), and Region Forecast 2020-2031

Cat Allergy In Humans Market size was valued at US$ 6,238.9 million in 2024 and is expected to reach US$ 12,004.0 million by 2031, growing at a significant CAGR of 9.8% from 2025-2031. Cat allergies in humans are caused by proteins found in a cat's skin cells, urine, and saliva. When these proteins are released into the air and come into contact with a person who is sensitive or allergic to them, they can trigger an allergic reaction. Symptoms of cat allergies can include sneezing, runny or stuffy nose, itchy or watery eyes, coughing, wheezing, and skin rashes.

The increasing trend of pet ownership plays a pivotal role in driving the revenues of market. As more individuals welcome cats into their households, the potential customer base for products and services geared toward managing cat allergies expands significantly. This rise in pet ownership leads to a higher likelihood of people encountering cat allergens, whether they own cats themselves or not. Consequently, there is a growing awareness of cat allergies, prompting more individuals to seek diagnosis and treatment. This surge in demand for solutions to manage cat allergies fuels innovation in the development of various products, ranging from medications and hypoallergenic pet supplies to air purifiers and allergen-reducing cleaning solutions.

Moreover, the escalation of awareness about cat allergies and the importance of diagnosis significantly propels the growth of market. As public knowledge about allergies expands, more individuals become cognizant of the various symptoms and triggers associated with cat allergies. This heightened awareness prompts those experiencing allergic reactions to seek medical attention and proper diagnosis. As a result, the market experiences an uptick in demand for allergy testing, consultations with allergists, and related medical services. However, limited treatment options and incomplete allergen elimination from indoor environments can hinder the growth of the market. Meanwhile, ongoing research and development of more effective allergy medications, immunotherapies, and other treatments can contribute to a growing market as people seek better solutions for managing their allergies. Key manufacturers are innovating excellent solutions to cater to the end-users. For example, in February 2020, Nestlé Purina developed the first and only nutritious and balanced dry cat food that reduces the allergens in cat hair and dander.
