If your vet hasn't done blood work or x-rays, that may be the next step. Some cats can have a Fever of Unknown Origin, and it often responds to IV fluids. Inflammation of mucous membranes, such as the anus, can be caused by infectious or inflammatory disorders, and blood work may help to see if this is the cause, including CBC, chemistry, and testing for FeLV/FIV. Internal parasites or constipation can cause reddness of the anus.
