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 realio, trulio, little pet dragon.”

Let me float in it like a fish.”
