I'm sorry to hear that your cat is sick. An elevated white blood cell count is normally a sign of infection, although less commonly it can also be caused by certain types of cancer like lymphoma or leukemia. If your cat is not eating or pooping, then she definitely needs additional care - I would recommend talking to her vet about options for further testing and treatment, or asking for referral to an internal medicine specialist if needed.

A normal white blood cell count in cats typically ranges from 4,900 to 20,000 per microliter of blood. However, that "normal" range could vary depending on the age of the cat. In addition, each lab has its own range of lab values, so without seeing the lab report, I can't say for certain her WBC is high. Based on the normal range I mentioned above, it's only very slightly above normal, so it wouldn't be considered significant. At 15 years of age, there are lots of things that could cause a cat not to eat, like dental disease, cancer, or kidney disease for example. If she isn't eating or pooping, I recommend taking her back into your vet.
