I have 5 kittens and the mother is a first time mother. I just gave away two of her kittens. A boy and a girl. They are twins. My cat had two sets of twins. They were born by emergency c section on april 25th 2013 and she has been the best loving mother. She has been meowing and calling for her missing kittens in a more distressed pitch. I want to know if she is missing her babies and depressed by their loss. They have been gone for about two hours now. How long will my cat miss them for if she even misses them at all?. I am also very upset and miss them terribly already does my cat sense this and does it add to her distress?. Please help me to understand. Thank you.
