It is a normal thing now because of the number of people trying to dispose of pet poop.
I have wondered why people are putting it on the outside of their car or vehicle.
I usually see it on the rear wiper blade, it is an easy way to hang the little pet poop bag.
Obviously, people don’t like the smell in the car and it is not always easy to find a place to dispose of the pet poop.
Hence, there must be some information people are trying to find.
