4. No problem

Just let her or him figure it out. It very well may have been abandoned early bcz dead momma scared momma...i.e. it had no chance to be trained by momma. Don't sweat it. Also b sure box is small as to not overwhelm it. Don't over feed. Spend much time reassuring it and rub the tummy gently often. Stimulates the abdominal area. I was a licensed vet technician for decades. It will figure it out eventually. Just put yourself in it's mind. Right now it's scared freaked and instinctively won't defecate or pee if there's a threat to survival. And thank you. Kindness is always welcome especially for the ones that can't speak for themselves
