What to coat electrical wires to prevent cat bites?
To prevent cats from chewing electrical cords, here are a few methods:
1. Spray or apply lemon juice, chili juice, floral water, toothpaste, or similar substances to the cables. Cats dislike these pungent smells and will therefore avoid getting close to the cables. 
2. Use wire protection tubing, a device specifically designed to protect wires. It allows for easy adjustment of length and direction, making it very convenient and practical.
3. Secure the power cord to the wall to prevent it from dragging on the ground or at low places, which will also effectively prevent cats from chewing on the power cord.
Please note that the above methods are for reference only, and the actual results may vary depending on the situation. If the wire is damaged or exposed, it is recommended to replace the wire or take other safety measures in a timely manner.
