Examples of animal allergens:
* Saliva (dogs, cats, horses, etc.)
* Urine (cats, dogs, small laboratory animals)
* Serum (of blood)
* Horny flakes (desquamated skin)
* Epithelium (desquamated skin)
* Excrement (parrots, pigeons and others)
The impact on the patient's allergy occurs when inhaled dust. Most frequent allergic to cats, but the most severe forms marked with allergies to horses and small rodents.
