How much can I do for a neighbor's neglected cat?

There is a kitten/cat, a calico, who roams the neighborhood. I thought she was a stray because she was hiding under my deck for two weeks and I tried to find the owner with no luck.

It was a very cold spell and I luckily have a couple of heated houses on my back deck just in case, so she stayed in one of them. Finally, a neighbor a couple of houses down sent me a message through Facebook messenger that she saw her cat on my deck.

In talking to this young girl (probably 20's), she had five cats that she let roam. She now has two left. None of them had been fixed and this calico is no different according to the girl.

She works odd hours and if her cats don't come home to eat when she is home, she does not leave food out. Specifically, she leaves the calico out day and night in the cold weather with no protection from the elements and it may not get fed.

I tried talking to her about getting her fixed and I would help her with the cost. She said that she was going to talk to a vet about it but I have not heard anything further and I know the calico is not spayed.

She also mentioned that this cat does not use the litter box so that's why she leaves it out. I don't know if she took it to a vet to be checked for her litter box issues.

The calico has been coming over to my deck and yard even though I had not been feeding her. I would like to keep this cat to give it a better situation but I don't want to just take her. I see this calico running around the streets and I'm afraid she is going to get hit.

Is there anything I can do to help this cat or should I just leave it alone and whatever happens, happens, and I might find a dead cat or a litter of kittens under my deck?
