"my cat had a kitten yesterday at 8pm 3/5 it is now 1226am 3/7 she is still big like she may still have more. she is acting normal eating and feeding the kitten. should i be worried?"

Dear nene28, I would try not to worry too much. Often if its her first litter, its not unusual for the birthing to last longer than we think it should. I would suggest that you call your vet. Which I am not. Her labor DOES seem unique but hopefully all will turn out successful.

Gently feel her belly and see if you can feel anymore kittens.

If you're worried, then call or take her to a vet.
