Normally, pets are not allowed on public transportation, but some bus drivers will be accommodating, but they need to try not to affect others. Therefore, it is recommended that owners drive their own car or take a taxi when carrying a cat bag. It should be noted that cats that stay at home for a long time are easily frightened when they go out. For example, the sudden honking of a car horn or the noise of people on the road may trigger the cat's stress response. Therefore, it is best for the owner to put some toys that the cat likes to play with, as well as old blankets and other daily necessities in the cat bag. As long as there is a familiar smell, the cat will feel more at ease.
