If your cat gets scared and tries to run away while on a leash, immediately ensure their safety by holding the leash securely without pulling them back forcefully, as this can cause panic or injury. Speak to them in a calm, soothing tone to help ease their anxiety. Gently pick them up, if possible, and carry them to a safe, familiar environment. It's crucial to avoid exposing them to the same frightening situation again. Gradually reintroduce outdoor experiences in a more controlled, quiet setting, always prioritizing their comfort and readiness.
