A hard knot on a cat's tail

A hard knot on a cat's tail may be caused by external parasite infections, mosquito bites, or fungal skin diseases. It is recommended that the owner carefully observe the cat's situation to see if there are any other abnormal symptoms. If the hard knot on the cat's tail is slowly disappearing, it may be caused by a mosquito bite. If the cat also shows symptoms of itching, and white or black dots are found under the fur, it may be caused by an external parasite infection. If the hard knot area shows hair loss, dandruff, and the cat tends to scratch and bite, it may be caused by a fungal skin disease.

Caused by external parasite infections

If a cat often plays outside and its owner does not regularly deworm the cat, the cat is likely to become infected with external parasites. Parasites biting the cat's tail can cause hard knots. At the same time, due to itching, the cat will frequently bite and scratch its tail, causing the skin to become red. In this case, it is necessary to worm the cat externally promptly. After that, the cat should be dewormed externally every month and internally every three months.

Caused by mosquito bites

As mosquitoes feed on animal blood, they will also bite cats, causing red hard knots at the bite sites. The owner can observe the knot for a couple of days to see if it can disappear on its own. If the knot disappears, it was likely caused by a mosquito bite. To prevent cats from being bitten by mosquitoes, owners can use children's mosquito repellent lamps at home, which can effectively prevent mosquito bites.

Suffering from fungal skin diseases

If the hard knot on the cat's tail looks like a scab that can be easily scraped off, and is accompanied by dandruff and hair loss, it may be caused by fungal skin diseases such as ringworm. The owner should first isolate the cat and clean and disinfect the home to avoid infection. Then take the cat to the pet hospital for related checks. Use a Wood's lamp to illuminate in a dark environment, and there will be a distinct fluorescent green phenomenon. After diagnosing ringworm, follow the doctor's advice for treatment.
