Cats stop eating when they feel discomfort. I do not think your cat is experiencing sharp pain but he is experiencing dull pain like a headache. The best thing to do would be to have him examined by your veterinarian. Determine if this is related to uncontrolled diabetes or progression of the kidney failure. Fluid therapy is part of the treatment for either disease. This cat needs at least several days of hospitalization.
There is not a lot you can do at home. Hospice care can include oral anti-nausea medications, Pepcid, and subcutaneous fluids (fluids under the skin).
It is likely that refusal to eat is the first sign that your cat is starting to decline and it may be time to consider euthanasia in the next few days.
Consult with your veterinarian about treatment options and prognosis. They know your cat the best and can help you determine when the right time is to let him go.
