Plastic pet doors on the market just don't have style

and sizes of high quality window inserts that make it easy to add a cat door.
I agree with you, but several years ago, I installed a pet door in the door leading to the garage, so the cat litter box could be in the garage. We later got a [JOBSITE WORD]er Spaniel, and she learned to use the "cat door" to get back into the house when we returned from car trips. She would bail out of the car, run full speed through the garage, and go through the flap at approximately 20 mph, or at least it seemed like it. I was working in the garage, with the garage door up, so I put the cover over the inside of the pet door, to make sure the cat didn't escape. My wife came back from somewhere, with the dog in the car. (I bet you all see where this is going.) She stopped in the drive, opened the door, told the dog to get out, and go in the house. All I saw was a black blur as she sped by, just in time to hear "THUNK" and see her laid out at the base of the door. After a few seconds she stood up, shook her head, and looked at me as if to say "What the h*ll?"
Cut out the cat door template or make one by transferring its dimensions to a large piece of paper and cutting it out.
Demonstrate the door for your cat. Guide your cat through the door a few times to make it comfortable with using the door.

Be sure you make a pet door big enough for your full grown pet. Once you know the size, draw the dimension of the hole on the house door using the level or ruler for straight lines. Leave 2 to 3 inches at the bottom to retain door integrity. Use a jigsaw to cut the hole. On a hollow door, mark the outline on the opposite side in the same location and cut. Be sure the cuts match. If you bought a rubber door flap, use that as a guide for the dimensions of your cut.When we first moved in to this house, we couldn’t figure out the best place to put the cat’s litter box. The upstairs was mostly carpeted and the laundry room was small. The best place to have the litter box seemed to be the basement but we had a door that closed to the basement. After looking at cat door ideas and units, I decided that it wouldn’t be too hard to make my own. So, here’s a very simple tutorial for a simple DIY Cat Door.The cat door that you install should take into consideration the width of the cat at the present and also give good allowance for the future. You can make a good estimate by looking up the dimensions of a fully grown cat of similar species.One question my wife asked as I was doing this was, "Will adding more weight make it more difficult for the cat to move the door?" The answer is no, it will actually make it easier. If you think of it like a see-saw again, when un-balanced it is like having a person on one side and no one on the other side. If you want to move the see-saw it will take some effort (a lot of effort if that person is quite heavy). However once we balance the door it is like a see-saw with a person of equal weight on each side. If they keep the see-saw even and still it should be considerably easier for you to go over to one side and push or lift it. The makes use of functional and social technology to ensure that only approved felines can welcome themselves inside. An RFID reader is used to recognize the pet's collar tag and then the latch to the door opens. Optional features include a webcam and connecting the whole thing to Twitter—the creator of this particular device created funny messages (something like "Sadie is leaving to play poker with the crew") to document the whole thing and allow owners to stay apprised of their cat's whereabouts. Consider the safety of your pet. If you’re allowing your cat access to the outdoors, you are putting him at risk. Though many people believe that cats need to roam free to be happy, it’s completely possible to keep your cat content inside your house. If you choose to do that, you will almost certainly be giving him a longer life. No longer exposed to the dangers of cars, coyotes, poisons (inadvertent and intentional), traps (ditto) and contagious disease, your indoor cat will likely live years longer than a who roams the neighborhood. If you still want an outdoor cat, make sure he's microchipped, so if he gets lost, he's more likely to be returned home.
