TLDR Cats can get skin issues from things other than fleas, like insect bites, food, or allergens.
The document reviewed feline non-flea induced hypersensitivity dermatitis (HD), a common condition in cats characterized by pruritus and various cutaneous reaction patterns such as miliary dermatitis, eosinophilic dermatitis, self-induced symmetrical alopecia, and head and neck excoriations. Diagnosis was based on excluding other pruritic conditions and observing response to treatment. Treatments included immunomodulatory drugs, hypoallergenic diets, and allergen-specific immunotherapy. A study involving 161 cats indicated a potential hereditary background, with most cases presenting before 3 years of age. The document emphasized the importance of a thorough diagnostic work-up, including ruling out ectoparasites and conducting elimination dietary trials, as clinical signs were not pathognomonic. Diagnostic criteria developed by the University of Zurich improved sensitivity and specificity when fleas were ruled out.
