There are several things you can do to prevent your Bengal cat from getting into mischief while you are away from home:

1. Provide plenty of toys and mental stimulation: Make sure your cat has plenty of toys to play with, such as puzzle feeders, scratching posts, and interactive toys. This will help keep them entertained and prevent boredom.
2. Keep your cat indoors: It is generally safer to keep your cat indoors, as they can be at risk of injuries or other dangers when outside. If you do allow your cat to go outside, be sure to supervise them at all times.
3. Use a crate or pet sitter: Consider using a crate or hiring a pet sitter to keep an eye on your cat while you are away. This can help prevent them from getting into mischief or causing damage to your home.
4. Provide plenty of exercise: Make sure your cat gets plenty of exercise and mental stimulation during the day, so they are less likely to become destructive or mischievous when you are not around.
5. Consider getting a second cat: If you are often away from home and your cat is prone to getting into mischief, you may want to consider getting a second cat for companionship. This can help keep your cat entertained and prevent boredom.

By following these tips, you can help prevent your Bengal cat from getting into mischief while you are away from home.
