My landlord has a terrible fear of rats. Over the summer, a young stray cat started hanging around the brownstone meowing for affection and food. My landlord started feeding the cat, and even put a box for it to stay in, because he is convinced that having the cat living in front of our building will scare away rats. But now it's late fall and getting colder; the cat is looking more and more desperate and sad. I'm afraid it won't last much longer out there. So here's the question: having benefited from the cat's predicament, is my landlord now morally responsible in any way for the cat's eventual fate? Is he under a moral obligation to take the cat inside, or to a shelter, etc? Similarly, am I, having indirectly benefited, under any moral obligation to the cat?

I think so, it is not as though the costs of looking after the animal are immense. If one can prevent harm to a sentient being then one ought to, other things being equal.
