How can I get these kittens...?

So I really want a kitten. Yeah. Their are no shelters where I live and my dad hates cats.

But my houses tenant really wants a kitten also, so I'll get some help their.

I found a mother cat who I am fairly certain has a litter of kittens hidden in my neighbors house that are about a week old.

The neighbor...we don't talk to him, so I can't just ask "Do you have kittens?"

I am feeding the mother and father cats tuna, and I did the same thing to another mother with 3 kits when I was in Mexico, except I didn't get to catch/keep any.

Any tips on how to get these kits? They're to young now, but when they're old enough?

How should I do it? How can I get them out of the house/backyard?

And please give me actual answers, not the 'get them spayed and neutered' bullshivik.

I already know that. Geez.

And again, ADOPTING IS OUT OF THE QUESTION.
