My female cats nipple is dark brown and protruding

Thanks for reaching out with your question. It’s good that you’re keeping a close eye on your cat’s health and noticed this change. A dark brown, protruding nipple in female cats can have several explanations, so let’s go through some possibilities.



One common cause might be a benign skin change, such as hyperpigmentation, which can occur as cats age or after exposure to the sun. If your cat is pregnant or nursing, it might also be a normal part of lactation. However, if the change is accompanied by swelling, redness, discharge, or if your cat seems to be in pain, it could indicate an infection or mastitis.



In some cases, lumps or unusual pigmentation could suggest a more serious condition like a mammary tumor, especially in older, unspayed females. While mammary tumors can be benign or malignant, it's crucial to diagnose them early.



At home, keep the area clean and monitor for changes in size, color, or texture. If your cat is licking the area excessively, you may need to gently discourage this to prevent irritation.



Please watch for signs like sudden growth, pus, bad odor, or if your cat seems uncomfortable or unwell. It’s important to get these issues checked out promptly.



Given these possibilities, I would recommend scheduling a video consultation with one of our veterinarians on Dial A Vet. They can provide a more specific assessment and guide you on the next steps.
