Caution: Prior to installation, it is the responsibility of the user to consult all building codes which may influence the fitting of the cat flap and assess the suitability of a given installation. The user must also consider potential hazards present inside or outside the cat flap as well as the impact that subsequent modifications to your property may have on the existence and use of your cat flap. It is recommended that these assessments are conducted in consultation with a construction professional.

Manufacturer Recommendations:

  • For DIY installers, please note the use of power tools may be necessary. Safety equipment (gloves, eye protection, etc.) should be used. Consult a professional when necessary.

  • You may need to remove the unit at a given time if you move or change out units. If this is the case, do not glue the main assembly to the wall. This could result in the damaging of the wall surface upon removal of the unit.

  • A mounting adaptor and tunnel extenders are recommended for wall installations.


Step 1: Measure your pet from feet to shoulders. When installed, the top of the flap opening should be at least an inch above their back. If there is a drop-down on the outside of your wall, take this into account, as you may need a step or ramp.

Step 2: Select your installation location on the wall for the cat flap. This should be a convenient location for your pet to enter and exit the home.

Step 3: Using your pencil, mark a 6 ¼" w x 6 ½" h square on the wall. This indicates the position of the wall tunnel.

Step 4: With the appropriate tools, make a hole through the wall, ensuring that the tunnel is horizontal. Any slope downward from the inside to the outside of the home will ensure any rain runs out of the tunnel.

Step 5: Apply super glue to the four tabs of the tunnel extender. Fit the extenders together. When the glue has dried, place the weatherproof tape to the outside of the tunnel.

Step 6: Revisit Step 5 to bond all of your wall extenders together. Do not glue your tunnel to the tunnel of the cat frame. Just use tape when you get there.

Step 7: Take the mounting adaptor and drill four holes in it using a 4mm drill bit. These 4 holes are for the screws that will hold the cat door to the interior of your home. You can place the four screws where you like around the perimeter of the mounting adaptor.

Step 8 (if you purchased a mounting adaptor): Take the two shortest screws from the box. Using a washer, screw the mounting adaptor to the cat door frame.

Step 9: Place the cat door (with the adaptor if you have it) into the hole in your wall on the inside of your house.

Step 10: With a pencil, mark the positions for the four screws through the holes you have made in the adaptor. You’ll need to remove some material from your wall to allow the screw and washer, which hold the mounting adaptor to the entire frame, fit properly. This ensures that the adaptor fits flush with the wall.

Step 11: Drill four holes in your wall using a drill bit that suits the construction of your wall and your chosen screws.

Step 12: Tape your wall extenders to the end of the cat door tunnel.

Step 13: Place the SureFlap frame and the tunnel through the hole in your wall. Screw it in place (through the mounting adaptor if you have it).

Step 14: Take the exterior frame of the mounting adaptor (if you have it) and cat door frame and place it over the end of the tunnel.

Step 15: Mark the position of the two screw holes required to mount the external frame. Drill these holes in the wall.

Step 16: Tightly screw your external frame (and adaptor if you have it) to the outside wall. You can use small screws to hold the end of the tunnel extender as a way to help installation.

Please Note: It is recommended to place waterproof sealant between the tunnel and external frame to restrict water from getting into the wall cavity.

Training Sessions 

Getting Started: Some pets will take longer than others to acclimate to their new door, so patience is key! Never push or shove your pet through the door (this will only develop negative feelings). Instead, follow these training tips + tricks to help introduce your pet to the door gradually.

Limit training sessions to no more than 10 minutes at a time. Two well spaced out sessions per day should be the maximum.

Hold the flap all the way open for your pet at first; then a little less each subsequent time so your pet learns to push through on their own. Stay consistent with verbal encouragement and treats for best results.


Teaching Your Cat to Use Their Door

Step One: Introduce your cat to the door by putting your hand through it so they know how it works. Have them inspect the new cat flap to get used to the look and smell (this is a great time to program your cat’s microchip!).  

Tip: You can wipe your cat’s face or body with a cloth and wipe the door with the same cloth to give it a more familiar scent. 

Step Two: Some cat doors make a slight clicking noise when opening and closing which can scare timid cats. Try manually opening and shutting the flap slowly to familiarize your cat with this noise. 

Step Three: Get your kitty’s favorite treats or toy ready! Start by using a treat to encourage your cat through while holding the flap open for them. Once they are comfortable, start lowering the flap on them as they walk through for their treat.

Tip: Be sure to train your cat using the actual door height - meaning raise the door enough so it resembles how high it will be once installed.

Tip: If you have a door with non-removable magnets, putting some painter’s tape over the magnets can help decrease the magnet attraction strength temporarily for training purposes.

Step Four: Always make sure to reward your cat with praise (and maybe another treat) when they pass through the door.  Remember: training can take a considerable amount of time. There is no standard practice as every cat is unique.


Quick Tips

- For especially timid cats, temporarily tape it up out of the way while they get used to the idea of walking through the tunnel.

- Clear flaps may confuse pets as they might think the flap is a window. Try putting a piece of masking tape on the clear flap to distinguish it from a window and reinforce to your pet its use as a door.

- Magnetic and weighted flaps have additional weight which may be difficult for your pet to push through. Fix this problem by gently pushing the door to assist your pet as they go through or removing the magnet until your pet gets used to the full weight of the door on their own.

- If you plan on installing more than one pet door, use the same flap if possible for consistency.

- Electronic flaps make a small clicking noise when the flap is activated that may frighten timid pets. The best way to remedy this problem is to positively reinforce this sound in your pet’s mind.

- Praise your pet when they come near the door and hear the activation noise.

- If this does not work, disable the electronics with “training mode” and have your pet use the door manually for a week or so while getting acquainted with the door.

- Consistency is key! Stay consistent both in your training methods and your choice of pet doors. If you have multiple pets the first to learn will often demonstrate  for the others!

- When your first lock the flap shut, introduce your pet slowly rather than letting them “learn the hard way” by running into it.
