How owners can prevent being scratched by their cats:
It's recommended to keep domestic cats indoors, not let them roam freely. Free-roaming cats go out to play every day and come into contact with stray cats, so if a free-roaming cat bites its owner, it will definitely need to be vaccinated. Domestic cats, because they spend most of their time indoors, don't necessarily need vaccinations even if they scratch their owners; just make sure to trim their nails regularly.
Some pet owners have a habit of feeding stray cats. It is recommended that when feeding stray cats, if you are not familiar with the cat, do not directly touch it with your hands. First, use your sleeve to test the cat's reaction, and then decide whether to continue touching it.
