The study shows works of numerous authors considerable variability organ localization of tumors in different animal species. 135 cases of neoplasms of different localization were analyzed. Among the animals that had tumors, there were dogs, cats, rats, guinea pigs, gerbils, hamsters, hares, rabbits and reptiles. The largest proportion were dogs and cats. The average age of dogs with neoplasms ranged about 8 years, cats – about 9. The number of dogs with neoplasms up to a year was less than that of cats. The level of detection of tumors in dogs remained equally high throughout life, and in cats gradually grew to 10 years and was a maximum of 13 years. It is shown that irrespective of the type of small animals kept by the inhabitants of Kiev, the greatest percentage of tumors falls on the skin and the mammary gland. In dogs, skin tumors are placed in the first place, while in cats and rodents, neoplasms of the mammary gland are on the first place. Frequent in dogs were neoplasms of testes, whereas in cats this pathology was not recorded. In dogs and rodents ovarian tumors had a significant percentage. Ovarian tumors in cats giving place colon tumors. In dogs and cats almost at the same level recorded tumors localized in the mouth. In addition to these noted a tumor of the uterus, spleen, kidneys, lungs, eyes and more. But the frequency of detection was less than 3% of cases. Features of organ localization of tumors is important for understanding the tumors nature.
