Cribriform mammary carcinoma is a malignant neoplasm, characterized by aggressiveness in the species, despite this, there is a shortage on the subject and discrepant information on some topics. Revealing the importance of publications on the subject for improving the quality of care and treatment instituted by the veterinary oncologist. The present study aimed to report the case of a feline patient, castrated late, diagnosed with cribriform breast carcinoma. During the course of her treatment, despite having undergone a bilateral radical mastectomy surgical procedure and the institution of an adjuvant chemotherapy protocol together with a cyclooxygenase inhibitor, as indicated in the consulted literature, the patient presented local tumor recurrence, being assessed as inoperable. It is concluded that the prognosis is poor, regardless of the treatment protocol established, as local recurrences and distant metastases occur almost invariably.
