A cat's nipple may become swollen due to pregnancy, lactation, or a potential infection such as mastitis. It can also indicate hormonal changes or a benign or malignant growth requiring veterinary attention.
Why is a cat's nipple swollen? - in detail
A swollen nipple in a cat can be attributed to several potential causes, each requiring careful attention. One of the most common reasons is pregnancy or lactation. During these periods, hormonal changes lead to the enlargement of mammary glands and nipples to prepare for nursing kittens. This is a natural and expected physiological response. However, if the cat is not pregnant or nursing, other factors must be considered. Mastitis, an infection of the mammary gland, is a serious condition that can cause swelling, redness, and pain in the nipple area. This often occurs in lactating cats but can also affect non-lactating ones due to bacterial infection. Trauma or injury to the nipple or surrounding tissue can also result in swelling, which may be accompanied by bruising or discomfort. Hormonal imbalances, such as those caused by false pregnancy or certain medications, can similarly lead to nipple enlargement. Additionally, tumors or cysts in the mammary glands are a potential concern. While some growths may be benign, others could be malignant, such as mammary gland adenocarcinoma, which is more common in unspayed female cats. Early detection and veterinary evaluation are crucial in such cases. Allergies or skin irritations, though less common, can also cause localized swelling around the nipples. To determine the exact cause, a veterinarian may perform a physical examination, blood tests, imaging, or even a biopsy. Prompt diagnosis and appropriate treatment are essential to ensure the cat’s health and well-being.
