Do cats (Felis catus domestica) suffer from environmental allergies

96% of the samples were positive, of which 74% were polysensitized cats. Most cats (90%) were sensitized to dust mites and storage mites. 23% were sensitized to weed pollen (Rumex crispus, Plantago lanceolata, Artemisia vulgaris, Chenopodium album, Parietaria officinalis, Taraxacum vulgare, Urtica dioica, Ambrosia artemisifolia and Ambrosia elatior). Almost 21% were sensitized to tree pollen, mainly pollen of Platanus (15%), Olea europaea (14%) and Ligustrum vulgare (11%). Grasses (Phleum pretense, Lolium perenne and Cynodon dactylon) account for 19.5% of the positive. No cat tested positive for fungal allergens (Aspergillus fumigatus, Alternaria alternata and Penicillium notatum). Environmental allergens that cause human disease are relevant for our domestic cats. The treatment of choice is to avoid contact with allergens. The only etiologic treatment is specific immunotherapy according to the levels of IgE detected.
