Q. Six year old calico, has diarrhea. Took to vet on Mpnday, blood work good. Has a very sore bottom, and I think that is why she is not eating.
A. Withhold food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet (1:1 ratio of plain boiled boneless chicken and plain white rice). Feed in small, frequent amounts waiting at least one hour between feedings. Serve warm or mix in a teaspoon of baby food to stimulate the appetite. Continue feeding until the stool is normal. Transition slowly to the regular diet. If the diarrhea doesn’t stop or the appetite does not return, recheck with your veterinarian.

A. Cats are notorious for hiding pain from their owners, so a cat not wanting to eat means that there is serious disease progression already. I am not convinced that a sore rectum is enough to cause a cat to not want to eat, and the diarrhea is most likely the cause of the sore rectum.
I would inquire about getting appropriate medications to treat the diarrhea and potentially subcutaneous fluids because it sounds like your cat may be dehydrated and need a nutritional boost to get better. I also recommend a low fat food such as Hill's Science Diet I/D or Purina EN Gastrointestinal.
But like I said cats don't typically not eat unless there is something major happening and a follow-up visit to the veterinarian for additional more involved diagnostics is HIGHLY recommended in this case to look closely at the small and large intestines for abnormalities. If this were my cat the next logical steps for me would be to do a radiograph and potentially an abdominal ultrasound.
