The main way to prevent Siamese cats from turning black is to increase the temperature of the cat’s living environment, and at the same time take measures to keep Siamese cats warm, especially the face, nose, tail and other parts with lower temperatures. Because the main reason why Siamese cats turn black is due to temperature changes. When the temperature becomes relatively low, the body temperature of the cat's tail, limb ends, face, nose, and ear tips will also be lower, while the body temperature of the trunk and lower abdomen will be higher. Therefore, the tail, face and nose will become darker.
