Oh my she is not going to put up with claw clipping, I see.
Yes, there are two types of posts which will file her nails
ONE IS CARDBOARD BUT leaves a messy residue when she scratches.
The other (which I have as I own 5 clawed kitties) has sisal rope posts. They LOV E it and I have never had to trim their nails.
Any pet supply will have them. I got mine on ebay.
Sincerest best wishes,
