Help for wood chewer

Help ! I have a wood chewer that is about 13 yrs. old .I got her at around 4 yrs. of age. This started right away. I know, its been awhile and I still haven't really found a way for it stop.
She does this chewing on corners of wood, coffee table, trim on doors, everything wood ! She seems to do it for attention for food. Sometimes I think she does it just because.....
When I got her she wasn't spayed but was declawed.

I can't leave her roaming the house at night....she would tell me she wants food by knocking something off or chewing. She does knock things around to get my attention also.

I am crating her at night. I don't want to. This is crazy. I have 2 other cats.
I recently started on feliway to help with another cat that is spraying. this has nothing to do with each other. Hope this will help ????

thats so weird my cat does the same thing.. she'll chew on wood and loves to chew card board.. i have never found a solution to this yet but i am excited to see if ayone knows what to do.. good luck.. i'll keep you posted if i find anythig out..

Oh yes, cardboard too! She has chewed on my woodwork around door frames.
The first night I had her, I put her in a room(carpeted) by herself and she chewed a hole in the carpet about the size of an apple, hence I can't put her in a room by herself, she would chew her way out ! I love her to death....

I'm sure hoping the feliway will help. I just started it today in another room where they spend a lot of time looking outside. If I have my back to her and don't respond to a (grunt) she will nibble on anything she can to get my attention. Pretty frustrating, but I've had to crate her at night down where I can't hear her. It's just too much. When i let her out, she heads for the kitchen.
Sure hope I can stop this - everyone I talk too thinks its all too weird ha !
thanks
