A pet door or pet flap (also referred to in more specific terms, such as cat flap or dog door a.k.a. doggie door) is a small portal in a wall, window or human door to allow pets to enter and exit a house (or other structure) 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.

With a little black kitten and a little gray mouse,
And a little yellow dog and a little red wagon,
And a realio, trulio, little pet dragon.”

That the shades of holy men
Who have failed, being weak of will,
Pass the Door of Birth again,
And are plagued by crowds, until
They’ve passion to escape.””
