This is such a sad story, I had to ask. My friend at work had a mother cat who had 5 kittens and lost them all in 3 weeks. She feels terribly guilty about the time she left them alone and thinks there is something she could have done to save them if she was there. Worst of all, her mother cat will not stop guarding the couch where she had the kittens, and she walks around the house sniffing and moaning as if looking for the babies. She won't believe they're gone. I feel so bad for her. When I had my sad litter of faders at least one lived. She said her cat was an excellent mother, very loving and attentive, and tried her best. What can be done for this poor sad little mommy? It's heartbreaking.
