Cats don't have hopes and dreams to be crushed, we can hardly compare cats to people.
Perhaps this is why I like cats, though I've never wanted to own one (they keep showing up in my life anyway, via housemates and partners): they seem like independent beings, tolerant of humans for the services they provide, but pursuing their own interests; wild creatures, only pretending to be domesticated.
I've yet to meet the cat who loves indoor life so much they won't bolt for the door if it's left open.
