You can take your cat on the highway while driving. If the owner needs to travel, he can take the cat with him or take the cat on the highway. However, please note that it is best to have someone take care of the cat or prepare a comfortable and strong air box for the cat. Put the cat inside and do not let the cat run out and interfere with the owner's driving to prevent traffic accidents.

Notes on taking cats on the highway:

1. Prepare decompression toys for cats so that they can relieve boredom and relieve stress on the road.

2. Remember to close the car window, or open only a small crack to prevent cats from jumping out of the window.

3. It is best to have someone look after the cat to prevent the cat from interfering with the driver's driving.
