I don't know if you remember my last question where I mentioned I still have a litter (and the mom has been spayed now, so that question's issue has been resolved, at least for me) Well we had 3 kittens remaining from the litter, from which we, well, my mother was going to keep 2 of them.
They suddenly disappeared--all three of them--(around 8 days ago) and we don't know if they got lost together or they were taken. 2 days ago one of the kittens returned, all dirty and skinny(which makes me think maybe they got lost) and for some reason she is really scared when my mom tries to interact with her. She was the most docile of the litter, pure love. But now it seems she's terrified of getting petted. My mom bathed her and put her in one of the restrooms with a litter box and food. She seems to do alright while she's alone but runs and hides at a minimal sign of a human approaching.
How can I advise my mother in handling the situation?

Kitten is being playful again and loves being with my mom. I don't know if she misses her 2 brothers, but so far she's been doing great! Gained weight and became an even more loving cat. Thank you all for your answers! I really appreciate it!
