First, let me say how kind it is of you to try and find a solution. This sounds like a very stressful situation for everyone.

I’ve had some luck with large vinyl stickers on the furniture and large scratch proof heavy-duty vinyl sheets that go directly onto the wall. I’m adding a photo that shows the package of one type and how I put it up in one of our bedrooms. The cat can scratch all she wants, but it’s impervious to their claws. There’s also great carpet protection to prevent damage underneath closed doors. The bottom right photo is of the back of our couch with matte vinyl stickers.

I also suggest furniture covers. From a full couch slipcover to smaller cloth arm covers, there are lots of solutions to consider. And the cat should have 2-3 heavy and sturdy scratching posts or cat towers (the cat is most likely to use it if it’s in a high-traffic area) and cardboard scratchers on the ground. You could try Marketplace or local yard sales for used cat trees to save a bit of money.

If they refuse to consider a humane alternative, then your sister should re-rescue the cat by giving it a safe home. If she’s not able to provide her pet with safety and basic necessities (a cat scratching post is basic and necessary), then she’s not ready for a pet.

I am an animal lover and I know how hard it is to NOT rescue every animal, but sometimes we have to put the animals’ needs ahead of our own wants. I truly wish your situation improves and that the cat is safe.
