It could indeed be stress-related, or caused by an as yet undetected
parasite or illness. From your description, there does seem to be
something very wrong with her gastrointestinal system.

Keep her off food for another 12 to 24 hours, but make sure she has
water (not milk or any other drink, just water) to prevent dehydration.
After that, feed her small portions of equal parts of cooked rice and
chicken baby food, and keep lots of water for her.

If the diarrhea has evidence of blood, or is fluid, or has a very foul
odor, don't wait until Thursday. Call the vet ASAP, ask to come in right
away, and ask about the possibility of a payment plan or paying on a
later date. If the vet refuses, keep calling others and don't stop until
you find one who will. But get that cat in as soon as you can if any of
the aforementioned conditions exist; they are possible signs of a very
serious illness that must be attended to urgently.

Diarrhea will kill her before Thursday.

Hi,
I am not a vet, but I sure have had a lot of cats.  Over the years my
cats have had 4 litters.  I never observed a phenomenon of diarrhea
such as you are describing that was related to nursing.  I really just
wanted to emphasize a point in one of the earlier replies.

Contrary to popular opinion, it is never advisable to give a cat
milk.  It promotes diarrhea.  As the other author indicated, water is
the drink of choice.

If I were in your position, I would make an appointment to see the
vet.  I would also ask about the advisability of using products
available over the counter to control the problem.  Under the
circumstances, you might find out the vet's opinion on weaning at this
time.

We rescued a kitten, not long ago, who was 5-6 weeks old (we
thought).  There was a problem contacting my vet due to a weekend and
holiday.  The kitten obviously didn't know what to do with cat food,
but he was obviously hungry.  I dabbed my finger in the food and got
the kitten to lick it.  I slowly lowered my finger into the food, and
the little guy discovered he could lick that too.  The plate was clean
shortly thereafter.  We were careful, however, not to feed him a lot,
and waited around 6 hours before we fed him again.  He didn't
understand about drinking water either, but the same technique worked
for that also.

Linda,

Your cat needs to go to the the vet right away. That kind of diarrhea is
very dangerous. It could also be a sign of something like feline
distemper or parasites which could affect the kittens.

Having a litter can be expensive -- but when you chose to take on that
responsibility you've got to beg, borrow, or ask the vet to delay
payment, but your cat cannot wait for medical treatment.

I would also NOT withhold food. You can do that to dogs, but not to
cats. Cats can develop liver problems from not eating. Our cat had a
condition which is treated by fasting dogs, but never cats because the
risk is too high.

What are you feeding her? Have you changed food recently? Nursing moms
should be on a good quality kitten food. They need the extra nutrients.
Our vet had us change our mom-cat over slowly to not upset her system.
Hope your cat is eating wet cat food for the extra moisture.

Let us know what happens.
