I don't understand what's wrong with my cat. She's an outdoors cat but she lives in our yard where it's fenced around and her kittens that she gave birth to was in her little bed that we got for her and now that kittens just disappeared the next day that we saw them. We can't find the kittens anywhere and we don't know where she moved her kittens to. She seems to ignoring them and going on with her own life like she never had them. She was very loving the first day and now she neglecting her kittens and I'm afraid if I can't find them, they might die. Is this normal or is she just hiding them from us to protect them?
