Recently. I found this cat in my neighbourhood and it seemed she was quite furious and scared due to the weather outside or maybe she was searching for food. Quite often I see many stray animals under the car maybe it is because they find it a safe and warm place. In my opinion, one should not disturb them if they find any stray animal sleeping or just sitting beneath their car as they do not have any shelter like us and are dependent on humans.
Rather one can always feed them with food and provide them milk or water just for a noble cause.
