Safe plants for cats that can grow indoors and in dark places?

I want to give my boyfriend a plant or something for his place. He has a very sweet cat and I don't want his kitty eating it and getting sick. Also he typically leaves his room without a lot of lights and the curtains drawn, so I need something that's not temperamental. Just a plant he can water and it wont die on him. I think a plant would provide some better air for his place. Can anyone help me out I know this is specific but anything if helpful
