My Buddah sarted having contractions about 33 hours ago. They subsided for about 3 hours yesterday afternoon and started up again in the evening. They are not as intense as before. The babies are still moving a lot. Mom seems tired, but not stressed. She gets up periodically, goes to the litter box, or cleans herself, sits and looks at me, then goes back to her bed/box and sleeps in between contractions... It's her first litter. I've never been thru this with a cat before. I've been told I'm worrying too much. Please Help!!
