There are three main reasons why a cat’s balls turn black. The first is normal pigmentation. For example, the cat’s own color is black, or it is a Siamese cat that is partially black. This is normal. The second is that the cat may suffer from scrotal inflammation, which is usually accompanied by abnormal symptoms such as testicular swelling and redness. The cat will also constantly lick the testicles, leading to testicular ulceration. You need to consult a pet doctor in time for medication. The third type is that the cat has just undergone sterilization surgery. It may be that the blood oozing from the wound is dried and the scabs form, causing the testicles to turn black. Usually, the scabs at the cat's wounds will fall off on their own in about a week.

1. Normal pigmentation

If the cat has no other abnormalities except for the blackening of its balls, it may just be normal pigmentation. For example, if the cat itself is black in color, or if it is a Siamese cat that is partially black, as long as the cat has no obvious abnormalities, the owner does not need to worry too much.

2. The cat has scrotal inflammation

If you touch the cat’s balls and find abnormal symptoms such as redness, swelling, heat and pain, then the cat’s balls may have turned black. Cats suffering from scrotal inflammation will continue to lick their scrotum after the disease, which will worsen the condition. In this case, you need to consult a pet doctor immediately. Generally, you need to use antibacterial drugs for treatment. At the same time, put a collar on the cat to prevent it from licking the affected area and the drug. The normal color can be restored after continuous medication for a period of time.

3. Scab after sterilization

If the cat has just undergone sterilization surgery, the blackened eggs may also be the scab left by the wound healing. As long as the cat has no other abnormalities, the owner does not have to worry. The scab will fall off automatically after the cat's wound is completely healed. However, if the cat has other abnormalities, the owner can also take the cat to the pet hospital for examination, and conclusions can be drawn through specific clinical examinations.
