What is feline superfetation? — 9 Comments

  1. I believe this just happened to my cat. At one point during her pregnancy she was acting like she was in heat again and the neighborhood Tom’s were coming around again. She just gave birth and two of the kittens were stillborn and looked underdeveloped. One of them was born in a gush a fluid but its sac was fully intact with the placenta and everything. I had to struggle to break the sac as it was very thick. Neither kitten ever breathed or moved.

  2. Thanks for writing about this Michael. I did not know that the two pregnancies could develop alongside each other. I am aware that females can have different fathers to each kitten in one litter, and they can hold a pregnancy in abeyance when times are hard, but this is a new, amazing fact for me. Truly incredible. Mother cats must be some of the most capable in the world.

  3. Thank you for writing about this, Michael. I had never heard of this happening. I had no idea what the word ‘superfetation’ meant. Ten percent of pregnant cats coming into heat sounds like any awfully high rate of occurrence. The outcomes definitely sound unfavorable. 😧
