Sheet vinyl/linoleum for incontinent cats can preserve the subfloor from urine. Ceramic and porcelain tile are also famous for standing up to cat urine. Scratches are the least of your worries. The urine is the most damaging and can cost the most when it comes to replacement.

Thank you for the feedback. Vinyl has been a product mentioned but I have always been adverse to the suggestion, mainly because I love the beauty and feel of natural products. Maybe I will have to change my views and expectations. I have an open plan area living room/kitchen/dining and was considering the hallway bedrooms as a continuation of the same flooring. Ceramic and porcelain tiles have been a consideration in the past with a special grout.
