To prevent rabbits from chewing on electrical cords, you can try several methods:
Cover the cords with protective sleeves or tubing made of materials such as PVC or flexible plastic.
Keep cords out of reach by running them along walls or securing them behind furniture.
Apply bitter-tasting deterrents to the cords to discourage chewing.
Provide the rabbit with appropriate chew toys and distractions to redirect their behavior.
Supervise the rabbit closely when it's roaming around areas with electrical cords.
Consider rabbit-proofing the room by creating barriers to prevent access to cords altogether.
