| As
much as you love your pet, being its gatekeeper can be a drag. Cats in particular
haven't quite figured out whether they want to be lions or lap animals,
so they're continually in and out. Made of plastic or aluminum, pet doors
have a waterproof flap and a lockable panel to keep out unwanted visitors.
So installing a pet door in an exterior door will give both you and your
pet newfound independence. |
| Do It Yourself
or Hire a Pro? |
 Installing
a pet door in a wooden door is easy even for beginners because it requires
minimal carpentry experience. A carpenter would charge about $80 to install
a pet door for a medium-size animal, but you can buy the door and install
it for less than $40. Installation takes less than two hours, so it's a
good project to tackle yourself. Cutting a hole in your door requires a
little planning, but the paper template that comes with the unit makes it
easy to lay out the cut.
If your door is made of steel
or fiberglass, it's a better idea to hire a carpenter. He or she will have
the heavy-duty saw and specialty blade required to cut through these dense
materials. |
Choosing
a Pet Door
To buy the right-size pet
door, get a rough sense of your pet's dimensions. This is not an exact science,
but measuring his or her chest with a cloth tape measure is a start. Most
pet doors have a flexible flap that your pet pushes to get through and a
sliding lockout panel to close the passage. Better models have weatherstripping
and magnets that hold the flap shut. For a sliding patio door, you'll need
a pet door designed as part of a full-height door panel that you insert
in the slider frame.

by Step Instructions: |
 Step
1. Tape the template:
Position the template so it's
in the center of the door. If you have a panel door, it should be a few
inches above the door's bottom rail. If you have a door with a high bottom
rail and and a small pet, you may want to use a different door.
On a flush door, keep the template about 4 inches above the door's bottom.
Tape the template to the door. The bottom of the pet door should be parallel
to the bottom of the door. |
 Step
2. Bore the corner holes:
Bore a 1/2-inch hole just
inside each corner of the template so you'll have a starting point to insert
your saw blade. |
 Step
3. Cut from hole to hole:
Use a jigsaw or keyhole saw
to cut from hole to hole. After you cut three sides of the opening, apply
duct tape across the cuts to support the scrap piece as you complete the
cut. |
 |
Step
4. Mark the bolt holes:
Use a torpedo level
or tape measure to position the frame, then tape it in place. Mark
the holes with a pencil, then remove the frame and drill the bolt
holes (one bit-size larger than the mounting bolts' diameter) through
the door. |
 |
|
Step
5. Assemble the door:
Insert the mounting bolts
though the inside frame, then the door, then the outside frame. Tighten
all bolts finger-tight, then finish with an adjustable wrench. Saw off the
excess bolt length with a hacksaw. Use a file or coarse sandpaper to remove
any sharp burrs on the bolt ends.
If your pet resists using
its new door, open the flap and tape it open. After a few days, lower the
flap halfway. Gradually your pet will figure out that pushing the flap opens
it. |

Hire a Pro
A carpenter can do the job
in about an hour, including setup and cleanup. Since it's a small job,
consider waiting to hire a carpenter until you have a list of similar
carpentry work to make it worthwhile for both of you.
