Blackening Around Cat's Lips: Causes and Solutions


Zooplus DE

If your cat often leaves their mouth wet after drinking, this can lead to a buildup of bacteria causing a black ring around their lips. It's crucial to keep your cat's mouth area dry. Another possible cause is a fungal infection, which is typically accompanied by symptoms like hair loss and itchy skin. Also, an overly greasy diet can contribute to blackening around the mouth. Therefore, switching to a less oily cat food can be beneficial.

Causes and Solutions for Blackening Around a Cat's Mouth

1. Bacterial Infection: A common reason for blackening around a cat's mouth is a bacterial infection caused by consistently wet fur after drinking. If your cat frequently has a damp mouth, this area becomes a breeding ground for bacteria. To clean your cat’s "black chin", try using a medicated bath specifically designed for this issue. The medicated wash will react with the dark secretions, loosening them for easier removal. Once dissolved, rinse thoroughly with clean water. If you don’t have medicated wash, you can use warm water and soak the affected area, followed by gently drying it. Repeat this process several times.

2. Fungal Infection: Another potential cause is a fungal infection. However, these are usually accompanied by additional symptoms such as hair loss, skin irritation and itchiness. If you suspect a fungal infection, you can apply an antifungal medication to the affected area. In more severe cases, a medicated bath may be necessary to achieve full body treatment and ensure the infection is fully eliminated. This can help to reduce inflammation and eliminate fungal bacteria.

3. Dietary Issues: A high-fat diet can also lead to blackening around the cat’s mouth. If your cat consumes cat food with excessive oil content, it can cause their mouth area to turn black and also cause stomach problems such as soft stools. Switching to a cat food with a lower fat content is essential to address this issue and improve your cat’s digestive health. Opting for a less oily food will reduce the chances of greasy buildup around your cat's mouth.
