Domestic cats, Felis catus, are one of the major sources of indoor allergens responsible for various allergies, including respiratory disorders.1 There has been a steady rise in the prevalence of sensitisation to cat allergens,1 which may be manifested as atopic symptoms in a substantial proportion of allergic individuals.2,3 Cat ownership is fairly common in Western countries; almost a quarter of households in the USA4 and Europe5 own a pet cat, and it can be reasonably assumed that some of these households will have individuals who are allergic to cats. Consequently, management of cat allergens poses a substantial burden on these individuals.6,7
