Blackening of cat nails may be caused by damage to the nail bed or lack of light. It is recommended to trim your cat regularly and make sure it has enough outdoor activities and exposure to light.

The black nails of cats may be caused by dirty things, or they may be caused by fungal infections, interphalanitis, and blood congestion caused by injuries. The owner can try to clean the cat's nails first. If the black substance in the nails can be washed away, it means it is a dirty thing, just clean the cat. If the cat cannot be washed off or other symptoms are accompanied by redness, swollen nails, etc., it is recommended that the owner take the cat to the pet hospital for examination in time, and then undergo corresponding treatment after the diagnosis is confirmed.

1. Dirty things

If the owner does not regularly help the cat clean the litter box, which makes the litter box too dirty, the cat may step on some dirty things, which will stain the toenails. This situation is not a big problem. The owner can help the cat cut his nails short, then dip them with a toothbrush or brush to some pet shower gel, soap or toothpaste to gently brush off the dirt on the cat's nails, and then rinse them with clean water. In addition, the owner should also pay attention to maintaining the environment, change the cat litter regularly, and clean the cat litter box frequently, so that the cat will not dirty the paws when using its claws to shave the cat litter.

2. Fungal infection

If a cat has symptoms such as itching, local hair loss, dander, scabs, etc. in addition to blackening of his nails, it may be that he is infected with fungi. Because fungi are contagious, it is recommended that the owner be the best to isolate the cat and consult a pet doctor in time for medication treatment. Generally, antifungal drugs containing ketoconazole and terbinafine are needed.

3. Interptomitis

If the cat has symptoms such as redness, swelling, inflammation, and pus flow, then it is necessary to consider that it has interptomitis. This situation is usually caused by the owner's usual incorrect feeding management. For example, after taking the cat to play on a wet lawn, he did not wipe his toes with a dry towel, which caused the cat to suffer from skin diseases and eventually developed into interpinositis. It is recommended that the owner take the cat to the pet hospital for examination and treatment in time, insist on cleaning the wounds and spraying the cats every day, and strictly wear Elizabeth rings on the cats to prevent the cats from licking the wounds.

4. Blood stasis caused by injury

There are blood lines in the nails on the head of the cat. If it is hit or stepped on by a heavy object, it may cause bleeding, and the bleeding will turn black after a longer period of time. If the owner finds that the cat has a strong sense of pain and does not touch it, it is very likely that it is caused by blood stasis caused by the injury of the paw, so it turns black. This condition may cause nail necrosis and may cause suppurative inflammation, so it is recommended that the owner take the cat to the pet hospital for treatment.
