Harley was very happy of reaching home when he has a long travelling with me. Suddenly when we get down of the car, he tried to walking around for a while. When suddenly the door was close for his entering.
A pet door or pet flap (also referred to in more specific terms, such as cat flap, cat door, dog door, or doggy door) is a small opening to allow pets to enter and exit a building on their own without needing a person to open the door. Originally simple holes, the modern form is a hinged and often spring-loaded panel or flexible flap, and some are electronically controlled. They offer a degree of protection against wind, rain, and larger-bodied intruders entering the dwelling. Similar hatches can let dogs through fences at stiles. A related concept is the pet gate, which is easy for humans to open but acts as a secure pet barrier, as well as the automated left- or right-handed pet doors.
A pet door is found to be convenient by many owners of companion animals, especially dogs and cats, because it lets the pets come and go as they please, reducing the need for pet-owners to let or take the pet outside manually, and curtailing unwanted behaviour such as loud vocalisation to be let outside, scratching on doors or walls, and (especially in the case of dogs) excreting in the house. They also help to ensure that a pet left outdoors can safely get back into the house in the case of inclement weather.

The simplest type are bottom-weighted flaps hung from the top of the opening, which swing shut on their own, but may be spring-aided to increase wind resistance. These flaps often feature magnets around the edges to help keep the door closed against weather and wind. Some pet doors have side-mounted hinges like saloon doors. These pet doors usually have a spring or other contrivance to force their closure after the pet has gone through.
