Pet Door Options
From sliding glass door panels to smart electronic pet doors, we install every type of pet door in glass, doors, and walls.
A replacement panel with a built-in pet door slides into your existing sliding glass door track. No cutting into your current glass.
Most popular and affordable option
A pet door installed directly into an existing glass panel -- window, French door, or fixed glass.
Best for windows and French doors
For homes where a glass installation is not practical, a through-wall pet door provides an alternative.
When glass doors are not suitable
RFID-activated pet doors that read your pet's microchip or collar key. The door stays locked to keep out strays and wildlife.
Best security and convenience
Pet door panels built with the same double-pane insulated glass construction as your existing doors and windows.
Best energy efficiency
Smaller pet doors sized specifically for cats. Four-way locking allows you to set the flap to in-only, out-only, both directions, or fully locked.
Cat-specific with directional control
