I don't feel it's wrong to keep a cat in an apartment. I used to think so, but then I found out how many of them get hit by cars and hurt by predators. Plus if you're feeding them, they just hunt out of habit and don't eat what they catch. That doesn't seem to be a good thing for anybody.
Your cat probably naps all day while you're at work and is glad to have company and a warm, safe home with no shortage of food, drink, and toys.
My cats have scratching posts, one climbing thinge, and few toys. They prefer yarn, rubber bands, and Christmas bows as toys. They're happy.
Your cat is beautiful.
