I declawed two of my cats a dozen years ago. We declawed a very young cat who recovered quickly, and an 8-year-old who walked and jumped very gingerly for a few months afterward (declawing an older cat was an even bigger mistake, I now realize). I will NEVER declaw a cat again.
Yes, my declawed 14-year-old has spent her life tearing around the house, fake-clawing all the upholstery, and ruling the roost over much bigger cats with claws. She's okay, but I am not. I feel tremendous guilt for having allowed this unecessary mutilation to her. I took a dangerous risk with her health and happiness, and as a result, I unconsciously treat her like she's fragile; I have never gotten as attached to her as I am to my other cats. She's definitely my husband's girl, not mine. I guess I don't feel I deserve her affection, or something.
I didn't mean to get all psycho-babbly here, but I am trying to warn you that declawing can have a negative effect on YOU as well as the cat. Especially if you know you're doing something wrong, and since you've read this thread this far, you surely know....
We use Soft Paws on all our other cats. They do come off quickly on the kittens' tiny claws, but they stay on for weeks with our older cats. They are easy to use (especially if you have a partner to hold the cat) and as long as you distract the cat for 10 minutes after applying them, to let the glue set, they work really well. There's just no excuse for declawing while there are Soft Paws. They protect you and the furniture and they don't hurt the cat. And all those designer colors to choose from....
