Help!!! Lactating cat with diarrhea

Gracie's kittens are 4 weeks old.
Today I heard her having a bowl movement
I went to check on her and she had diarrhea.
It's bad and she's has not eaten in about 5 hours.
I even tried giving her treats.
Any suggestions on what I can do for her.

When Hina was nursing she had runny stool off and on.  I mixed in a little pure canned pumpkin into her food and it cleared up.  If your kitty still isn't eating for to long she needs to see a vet, especially since she is nursing.  Are the kittens doing okay?

[The kittens seem to be ok.
I never put treats out but tonight I but a
Small plate in the room hoping she would
Eat them. When I went in to check on her
The kittens were chowing down on the treats.
I have never seen them even act like they
We're interested in food. Boy did they make
A cute mess!!!

Oh man, i remember Hina's kittens were so messy at first.  Some of them started eating a bit of soft food at week four, some of them didn't start until week seven lol. 

Could your mama kitty have worms? I hope she gets better soon, not eating can turn bad fast.  I'd try to get some pumpkin, not the pie filling though.
