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.

Famous quotes containing the words pet and/or door:
“... instead of being a help meet to man, in the highest, noblest sense of the term, as a companion, a co-worker, an equal; she has been a mere appendage of his being, an instrument of his convenience and pleasure, the pretty toy with which he wiled [sic] away his leisure moments, or the pet animal whom he humored into playfulness and submission.”
—Angelina Grimké (1805–1879)
“Yet the day wears,
And door succeeds door;
I try the fresh fortune—
Range the wide house from the wing to the centre,
Still the same chance! she goes out as I enter.
Spend my whole day in the quest,—who cares?”
—Robert Browning (1812–1889)
