What precautions should I take when petting a stray cat to ensure both its safety and mine?

When petting a stray cat, it is important to take precautions to ensure both its safety and yours. First, approach the cat slowly and calmly to avoid startling it. Make sure to wash your hands before and after petting the cat to prevent the spread of any potential diseases. Avoid touching the cat's face or sensitive areas, and be gentle in your interactions. Consider wearing gloves to protect yourself from scratches or bites. If the cat seems agitated or aggressive, it is best to avoid petting it altogether.
