My kitties adore bark texture. They also prefer to stretch horizontally. So, they get logs. One lasts years here, and it's free nearly always.
My blind cat needed a declaw as he's a bit of a genetic mess, so his claws were growing sideways. We tried everything, even clipping and filing daily. But his poor feet were getting worse as he got bigger, and he couldn't walk without crying in pain. He's still more delicate when walking, and he prefers steps vs jumps to get up and down. But, he's a normal enough kitty now, and he's less protective of his feet. But, he does nip if he's scared.
