Abstract

Tumors of the lower urinary tract in cats most often affect the urinary bladder, arising from the cells that make up the bladder wall, which includes cells of the mucosa, submucosa, muscularis, and adventitia. Considering the limited literature data, especially in our area, this study was conducted with the purpose of determining the prevalence of tumors in the Croatian cat population, with determination of the breed, age, and gender of the affected cats. Histological slides from cats diagnosed with urinary bladder tumors from 2009 to 2023 were taken from the Archives of the Department. From the accompanying letter, data
on the breed, age, and sex of the animal was extracted. In the period in question, nine feline urinary bladder tumors were diagnosed at the Department of Veterinary Pathology. The majority of cats were domestic breeds (55.6%), female (77.8%), with an average age of 12.8 years (range 8-18 years, mode 18 years, median 12 years). The diagnosed tumors were predominantly of epithelial origin (66.7%), with all tumors from this group being urothelial carcinomas. A smaller number of diagnosed tumors were of mesenchymal
origin (33.3%): one lymphoma (11.1%), one round cell tumor (11.1%) and one myxosarcoma (11.1%). All diagnosed tumors showed malignant biological behavior (100%). This study presents an overview of bladder tumors in the Croatian feline population, providing insight into the age, gender and breed distribution of affected cats, as well as the prevalence and types of tumors that affect this pet. The breed and age distribution, as well as the frequency and types of diagnosed tumors, coincide with the literature data indicating that the Croatian cat population suffers from the same tumors as cats in other regions of the world. Contrary to the literature data, where male cats were more often diagnosed with bladder tumors, in our study the majority of affected cats were female. Despite the small number of cases in this research, the results represent valuable information that contributes to our knowledge in the field of veterinary oncology, and
can be useful in the diagnosis and treatment of feline tumors.
