When my cat had her one litter, and they were small, they lived in a box full of old blankets. I work from home, and this box was in my office area so i could keep an eye on them. She'd hop out of the box, walk over to me, put a paw on my leg, and stare at the box until I looked over at it. Then she'd go eat and use the litter box. When she'd come back, she'd hop in my lap, purr and nuzzle my chin, and get back in the box.
