Hello everyone, was just wondering if anyone has a cat that doesn't sharpen its claws? My 7 month old female pepe never seems to use her scratching posts. She runs around all the time, and is playful, and sometimes attacks the side of our couch, but i don't see her sharpening her claws. He brother does. They are indoor cats. Her claws are getting caught in the carpet now, so i have to clip them. Is this unusual?
