How do cat nipples swell? - in detail
Cat nipple swelling is a physiological process primarily associated with hormonal changes, particularly during pregnancy or pseudopregnancy. In pregnant cats, the surge in progesterone and prolactin levels stimulates mammary gland development, leading to increased blood flow and fluid retention in the tissue surrounding the nipples. This results in noticeable swelling and enlargement, preparing the mammary glands for milk production. Similarly, in cases of pseudopregnancy, hormonal imbalances can mimic pregnancy symptoms, causing the nipples to swell even without actual gestation. Additionally, swelling may occur during lactation as the mammary glands produce and store milk. However, nipple swelling can also indicate medical conditions such as mastitis, an infection of the mammary tissue, or other inflammatory or neoplastic processes. Observing accompanying symptoms like redness, warmth, discharge, or behavioral changes is essential to determine the underlying cause. If swelling persists or is accompanied by discomfort, consulting a veterinarian is crucial to ensure proper diagnosis and treatment.
