Cats get in and out of the house no matter what, they will get in any hole or any window opening they see even if it ruins the arranged dolls below. You will have to open the door whenever the cat decides to go out and then open the door again when he or she wants to get back in, the problem is the cats do this almost ten times a day. When the cat wants to get out, you open the door and a couple of minutes after, the cat wants to get in again which is very tiring for the owner. Cats let their owners do this all the time and it is very annoying. Cats check their territory and they do it often which leads to the continuous round of going out and in again. The cat will go out to check the door territory, get back in and then out again in a couple of minutes or even seconds. After checking the outside territory, the cat then checks the inside territory. This will be a never ending battle if the owner refuses to install a cat door.
Every few seconds your cat gets in and out, you will have to be there to open the door but with a cat door, you will no longer suffer that kind of frustration. The cat will get in and out through the cat door without your help. You need to know that cat doors are not for going out only as you can see. You should put a cat door that would lead to a litter box as well. You will also need a cat door to let the dog know that the room is only for the cat as you can see by the size of the door. The cat door is designed to be made small that only a cat can fit in.
You can also install a cat door in front of your home that would lead to the porch so that your cat can go wherever it wants to go without you having to open the door. This means that the cat can get fresh air in the porch, roaming outside the house but never outside the whole compound. Your cat will probably be content with the smell of the great outdoors. That is why installing a cat door to the porch door will be a perfect decision.
Cat doors are very easy to understand and they work very simple. You need for the cat door is only a hole, a rubber flap and you are all set, install the flap on top of the hole and everything will be in the right place. You can use a powerful magnet to hold the flap in place and you can see how the cat door works. All your cat has to do is to push the flap and it will not come undone as the cat passes through the cat door without worries.
