Clawing help!

Can anyone help me with this question-I have a 2 year old female, spayed but still has claws that is tearing holes in my carpeted stairs.  I have all kinds of scratching posts, pads, a climbing tree and even cardboard scratching blocks near where she first started on the steps.  I trim her claws about ever 2 weeks, but I'm about at wits end.  Any ideas?

Is there a specific spot she keeps going to?

One of our males used to love scratching the corners of our 2 bottom steps. We only got him to stop by putting double sided tape down where he scratched - he hated the sticky feel.

No, she is pretty much equal opportunity about where she scratches.

My Angel was about two years old when she adopted us.  For over three years, she had nothing to do with scratching posts or pads and never scratched anything in the house.  Then two years ago, she started scratching the woodwork near our bedroom.  I tried sprays and tape, but she still started scratching at 3:00 am until we would get out of bed and feed her.  As she always likes to play with paper and cardboard (and not sure anything would work), I purchased cheap cardboard scratching pads.  We then ignored her scratching near our bedroom.  I now have woodwork in extreme need of repair and cardboard scratching pads in every room, but she is scratching on the cheap pads and no longer tries to wake us for food with scratching, We will not react to her scratching and I also give her a snack before I go to bed.

I don't have an easy answer and I am certainly not a cat behaviorist, but try to ignore the scratching episodes (this is very hard to do) and keep trying to find what your cat may be using the scratching as a substitiute for - walks out doors, more play, or something else.

My cat does not react to catnip, but maybe catnip spray on your scratching posts, pads, a climbing tree and cardboard scratching blocks will attract your cat to where you want your cat to scratch.

I wish you luck.  Damage to a house by a beloved pet is so disheartening.
