The reasons why single women should not keep cats are as follows:

Owning a cat requires time and effort. Cats need to be fed regularly, their litter box cleaned, their fur groomed, and they vaccinated, all of which require the owner's time and patience.
Single women are susceptible to ringworm. Cats can carry fungi, and single women, due to their love for cats, often enjoy close contact with them. If their immune system is weak, they are easily infected with the fungus, leading to ringworm and affecting their health.
