The leading place among pathologies is occupied by conditions caused by the regular consumption of lactose. Veterinary gastroenterology as an independent area is a relatively young science, which is being improved from year to year. The increase in cases of visits to veterinary clinics of owners of cats with pathological conditions  of  the  intestines  and  stomach  causes  increased  professional  interest among veterinarians of general practice, as well as the felinological community. The article presents the results of studies proving the important role of food antigens in the early formation of degenerative processes of the intestine and stomach, leading to a significant deterioration in the standard of living of the animal with a subsequent fatal outcome. https://www.biotech-asia.org/vol16no4/clinical-and-morphological-manifestations-of-disorders-of-the-gastrointestinal-tract-of-cats-with-regular-consumption-of-lactose/ Atopy; Allergy; Domestic Cat; Food Antigens; Lactose Deficiency; Prevention
