What are the reasons for a cat's testicles turning black?

There are mainly three reasons for a cat's testicles turning black. The first one is normal pigment deposition. For example, if the cat's natural color is black or if it is a cat with localized black areas, such as a Siamese, this is a normal phenomenon. The second reason is that the cat may have inflammation of the scrotum. This is usually accompanied by symptoms such as swollen and reddened testicles, and the cat may constantly lick its testicles, causing ulceration. This condition requires immediate consultation with a pet doctor and treatment with medication. The third reason is that the cat has just undergone a sterilization surgery, and the change in color of the testicles may be due to bleeding and crust formation at the wound site. Generally, the crust will fall off by itself in about a week.

Normal Pigment Deposition

If there are no other abnormalities in the cat except for the blackening of the testicles, it may be just normal pigment deposition. For example, if the cat's natural color is black or if it is a Siamese with localized black areas, as long as there are no obvious abnormalities, the owner does not need to worry too much.

Cat has inflammation of the scrotum

If the cat's testicles are found to be accompanied by redness, swelling, and heat pain when touched, the blackening of the testicles may be due to inflammation of the scrotum. During the illness, the cat will also constantly lick the scrotum, exacerbating the condition. This situation requires immediate consultation with a pet doctor. Generally, antibacterial drugs are needed for treatment, and a neck collar should be worn to prevent the cat from licking the affected area and medication. After a period of continuous medication, the color will return to normal.

Scab after sterilization

If the cat has just undergone a sterilization surgery, the blackening of the testicles may be due to the healing of the wound left behind. As long as the cat does not show other abnormalities, the owner does not need to worry. After the wound has completely healed, the scab will fall off automatically. However, if the cat shows other abnormalities, the owner can take the cat to the pet hospital for inspection, and a specific clinical examination can only be concluded.
