Why is cat flea powder okay to contact skin but not human?

This statement is incorrect. Cat flea powder is not safe for contact with human skin. It can cause skin irritation, allergic reactions, and other health concerns. It is important to follow the instructions on the product label and avoid contact with skin, eyes, and mouth. If contact occurs, wash the affected area thoroughly with soap and water. If you experience any symptoms such as skin irritation or difficulty breathing, seek medical attention immediately.
