Cat fleas can live on humans for about 1 to 2 months, and their survival period will be longer in summer. Fleas have very strong survivability and adaptability, and they reproduce very quickly. Generally, fleas are present when pets are kept at home, so you must pay attention to environmental hygiene, clean and disinfect the room regularly. At the same time, cats should be bathed and dewormed on time to prevent fleas; cat litter boxes and litter boxes should also be cleaned and disinfected regularly.
