I found this article to be good, please read it if you have read the pro-declaw article. There are some things in this article that haven't been said in this thread.
After all this you must be reeling with information, but I'm glad you are leaning toward not declawing your cat. (By the way, screens are pretty cheap and easy to install, should your kitty mess on up early on in the training process.) I want to add a post to this, since you are still listening.
I have such a sense of pride over my seven year-old cat who is about the most trainable animal I've ever owned. I didn't think a cat could be trained but, just like with any other animal you need to approach it on their terms since you are training the cat to behave on your
terms. Training is a bit different with cats, but very doable.
Cats are intelligent. When Pixel is venturing off my yard, I only need call her and she stops, turns around and comes back. Often I do have to call her, but that work, and keeping a close eye on her when she is outdoors is something I do rather than keep her in. It must be done. My point is that a dog may be trained to never leave a yard; with a cat it just requires a bit more work.
It's the work involved that causes people to just go ahead and declaw their cats, I feel. They don't want to take the time to work with animals to make the living experience a positive one. I don't know, for me the process of training the animal is more rewarding than anything since essentially it is akin to communicating
with the animal: and the animal responds by adjusting. Imagine it that way if you will. You've essentially reached an agreement with an animal of another species. The argument that Now that my cat is declawed I'm not yelling at it all the time, is a poor one since it doesn't need to be a stressful process. Cats learn faster than you might think.
