Kittens may harbor fleas, small creatures that often live in the cat's fur like shadows in a dark corner, ready to attack. If a kitten has been in contact with an adult cat with fleas, or if fleas are present in the environment, the kitten can easily become a new host for fleas. 
The health effects of fleas on kittens should not be underestimated. They are like tiny assassins, biting the kitten's **, causing redness, itching, and allergic reactions, which bothers the kitten. More seriously, fleas can also spread diseases such as toxoplasmosis and bartonellosis, posing a greater threat to the kitten's health. 
As soon as fleas are found on kittens, immediate action should be taken. First, isolate the kitten and avoid contact with other cats to prevent further flea spread. Then, use a flea spray or detergent specially prepared for cats to thoroughly clean and disinfect the kitten's coat. If the situation is severe, it is advisable to take the kitten to the veterinarian in time. 
To prevent flea infestation, there are a number of measures you can take. Clean your cat's living environment regularly, keep it dry and ventilated, and create a clean and comfortable home for your cat. Change your cat's bed linen and towels regularly to keep them clean and hygienic. Avoid using harmful chemical cleaners to protect your cat's health. Trim your cat's hair regularly to reduce hiding places for fleas. 
In conclusion, as soon as a kitten is found to have fleas, immediate steps should be taken to ensure its health and safety. At the same time, in order to prevent flea infestation, you should also take some precautions to create a flea-free living environment for your cat.
