My kitten has diarrhea. Can I still train her to eat on a schedule?

At 8 weeks your kitten can be on a completely solid diet, and if you're feeding regular cow's milk it could be what is causing the diarrhea (cats can't handle milk.) If she doesn't drink a lot and doesn't like moistened food, you can try adding in a pet fountain or other running water source that may encourage her to play or drink a bit more. If she is still having loose stools even after feeding only her regular food, a vet checkup to rule out parasites and GI upset is also a good idea. If she is trying to nurse your other cat, just separating her for a bit can help deter the behavior.

Withhold food for so long in such a small kitten is not recommended. Diarrhea is a signs referring to a intestinal problem. It could be due to parasitic infestation (very common in kittens) dietary indiscretion, inflammatory disease, bacterial diseases or viral diseases. You could provide bland food (boiled breast chicken or white fish or gastrointestinal commercial diet) for a 24-36 but, if she continues to have diarrhea, might get dehydrated and therefore need to be checked by a veterinarian. Also if you can spot blood in the faces or if she get lethargic and not eating, or if she start vomiting, I would suggest to have her checked by your veterinarian as soon as possible. 
Good luck and post again on the forum if you need further advices. I hope my answer was helpful.

Given her age there are several things that cross my mind, but a common issue in these young kittens is parasites. Sometimes their parasite burden can be so high that they cannot maintain adequate glucose levels, and also can become uninterested in food and sometimes will begin vomiting. I would recommend deworming her. Also, it would be important to rule out signs of infection and/or sepsis. I think she needs to be seen by a veterinarian right away. Such a young and small animal can deteriorate quickly even with easy to resolve issues like gastrointestinal parasites.

She's adorable! I would be a little more concerned that she might have intestinal parasites or another disease causing her diarrhea. I would recommend seeing a veterinarian if you have not taken her in already. They can check a stool sample and she may be old enough for vaccines at this point. If there does not seem to be a medical issue you could try seeing how she does on just wet or just dry food - kittens sometimes do better on one vs. the other.

Oh my goodness, Gerdou is absolutely beautiful! Yes, it is typically recommended to not feed a cat for a period of time when they are suffering from diarrhea. It allows their stomach to settle, and then a bland diet is introduced after this period of starving. For a 56 day old kitten, I wouldn't withhold food for more than 12 hours. After this time period, feed Gerdou a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. Hopefully she feels better soon, but have her seen by the vet again if the diarrhea continues on the bland diet.

You might contact your vet to see if it is safe to increase the dose. If it is ProPectalin AntiDiarrheal Gel, this medication can be given every 8 hours. I would continue with either her current cat food or you can do boiled chicken breast and cooked white rice for a few days, but try not to change up her food too much as that can worsen diarrhea. Other causes of diarrhea in a kitten that may need diagnosis by a vet include food intolerance, food allergies, intestinal parasites, bacterial infection, or panleukopenia.

I would continue to feed her her normal kitten food. Diarrhea can be caused by sudden changes in diet, food intolerance, continued drinking of milk, intestinal parasites, bacterial or viral infection, etc. If the diarrhea continues for 48 hours, I would recommend that Lucy get checked out by the vet to determine the cause and start treatment. Make sure she gets plenty of fluids until the diarrhea resolves.
