I am needing to know from others, aprox how long after a pregnant cats belly drops will her kitties arrive? About two weeks ago i noticed that our female was more then looking a little fat and started to feel movement in her belly. This morning i noticed her belly has dropped...when i look strait down at her it looks like she might have a little extra weight, but her belly isn't full at the sides no more. will it be tonite? or in a few days?
