Nail care question

So Karma will NOT let me cut her nails. I have tried all the different tecniqes but to no avail it won't happen. I did discover though a few days ago that she likes to have her nails filed with a nail file.

Heres what happend. I was doing my nails, with her help of course. After I got done fileing mine I realized she had been triing to grab the file so I picked her up and started to file hers. She seemed to love it. She just sat in my lap with a big smile on her face and let me do all of her front claws.

What I want to know is this safe to do? If it is than I will just do hers when I do mine.

She really is a girly girl. Loves to help me color my hair, do my nails, put on make up and loves any thing pink.

I don't see how it would hurt
I think the only reason people don't file is because most cats won't hold still long enough for it.
Maybe she doesn't like the clippy noise that nail clippers make?

Ok that's the funniest craziest thing I've ever heard!
I dont see how filing her nails is that much different than clipping them. I wonder why she hates clipping so much??

Probably better than doing nothing at all.
