Couple Saves Kitten Trapped Between Walls

I heard a baby kitten crying for about 3 days, I thought it was outside of the house, but the day we discovered that was trapped in between the wall of the house, was exactly one day before we rescued it. When I opened the window trying to see outside for the baby kitten I heard it inside, so there's is how we found this baby kitten, now named "Katie", yes you right is a baby kitten girl. And we still have her because is inhuman leave her like that, alone in the streets. "No way", so what is the point to rescue her and leave it to die. Not even think about.
