Others are right about a scratching post. I like a carpeted tower that they can perch upon and nap (they like to be up where they can see their surroundings).
Best toys for mine are those that are on a wand with string and feathers or wand and felt that they can chase. They like to hunt and stalk, so try to play up that aspect by dragging it slowly on the floor. They also like to run around and just get crazy, so sometimes give them lots of fast action once they’re already engaged in playing.
Last tip: some people think cats are standoffish. They aren’t if you socialize them correctly. My kitties want to be around us all the time and love engagement. It’s all about how you raise them. Look for advice toward that end, as I have to get back to watching a show with my partner.
