Interior pet access or a door to the outdoors?

An interior cat door can connect a room to a litter area, while an interior dog door may provide access between living spaces. An exterior installation brings additional questions about exposure and how access is controlled. Decide where the pet will enter and what should remain separated before choosing the insert. The pet opening also needs to fit the main door’s panel layout rather than interrupt glass, hardware or important structural details.

If you want a split opening as well, compare Dutch doors and the available pet-door configurations. For a main entrance, start with an appropriate exterior door assembly and confirm the insert is offered for that design.

Before you choose

How do I choose a pet-door size?

Use the selected insert manufacturer’s measuring instructions for the pet’s height, width and comfortable step-over. Breed or weight alone does not determine the opening. Check the dimensions against the animal and the available area in the main door.

Can a pet flap be added to any door?

No. Compatibility depends on the door material, panel construction, glass, thickness and insert position. Confirm the available option for the chosen Rustica door before ordering or cutting an existing panel.
