You could do batting or perhaps even foam to make it more like a seat. I don't think any fabric on it's own is gonna endure kitty claws unless you'd get your hands to something slash resistant like foresters use when they're cutting with chainsaws. Even batting might be too thin unless you stack it up some. One option could be a rug cut in shape or possible EVA foam.
