The anal sacs are two small pouches located on either side of the anus. The walls of the sac produce a foul-smelling fluid that is released when a cat passes a bowel movement. The anal sacs or their ducts can become inflamed or infected due to a variety of causes. Most cats will respond well to pain relief medications and antibiotics. If a cat has several episodes of anal sac disease, and dietary changes and supplements or medication do not relieve the problem, the anal sacs can be removed surgically.

Anal sac tumors grow quickly and have a moderate risk of spreading to other parts of the body. Depending on the tumor’s size, your pet could develop signs of straining to defecate or produce thin ribbon-like stool. An increased calcium level in the blood is consistent with anal sac tumors, which can cause other signs and result in kidney failure. The best and most well-described local treatment for the primary tumor is surgery. Radiation and chemotherapy may be considered if there is evidence of spread.

Anemia is a medical term that refers to a reduced number of circulating red blood cells, hemoglobin, or both. It is not a specific disease, but rather the result of some other disease process or condition. The most easily observed and common clinical sign of anemia is a loss of the normal pink color of the gums. Several tests are performed on blood samples to diagnose anemia. If your cat's anemia is so severe that it is life threatening, a blood transfusion will be needed.

Anesthesia is accomplished by administering drugs that depress nerve function. It is important that you fully understand what will happen to your pet, and that you understand the risks. Anesthetic monitoring in a veterinary hospital is like that found in any human hospital. With today's anesthetics, many of which are reversible, your pet should be almost completely normal by the time of discharge.

Anisocoria is a condition in which the pupils of the cat's eyes are different sizes. Anisocoria is a symptom of an underlying condition or disease that needs to be identified and treated. Prognosis is guarded pending the diagnosis and treatment. Blindness may occur as a result of the underlying condition.

A cat that does not want to eat, or is not eating, is a cat with a potentially life-threatening medical condition. Many conditions can lead to the inability of your cat to eat or lose her appetite completely. It is important to find the underlying cause so that an appropriate treatment plan can be created. Appetite stimulants may be prescribed, and in some cases, a feeding tube may be placed by your veterinarian. Decreased food intake or any change in eating habits warrants investigation by your veterinarian.

Anthrax is a bacterial infection that rarely affects cats. It is not a new infection but has been revisited due to concerns about bioterrorism. Infection in cats usually occurs through ingestion of infected carcasses, causing clinical signs such as vomiting, diarrhea, and swelling of the face and neck. Treatment is highly effective in the early stages of infection.

Antibiotic-resistant bacterial infections are bacterial infections that are minimally or no longer responsive to commonly used antibiotics. Although these bacterial infections occur naturally, the frequent and/or inappropriate use of antibiotics accelerates the process. Cats with certain medical conditions may also be predisposed.

Antibody titers are sometimes needed to diagnose disease. Antibody titers reflect the level of antibody that the pet has made in response to exposure to a certain infectious organism. The titer is determined by sequentially diluting the serum and testing it against the organism in question. The more dilute the serum when it stops producing a positive reaction, the higher the concentration of antibodies present in the blood. Titers give support to a diagnosis, allowing more targeted treatment and more specific prognostic information, as well as identifying zoonotic disease (diseases transmissible between animals and humans).

Anticoagulant rodenticide is used to kill mice, rats, and other rodents. Poisoning occurs when a cat ingests rodenticide. Anticoagulant rodenticides cause excessive bleeding by interfering with vitamin K1 recycling in the body. Vitamin K1 is needed for the body to make certain clotting factors that enable blood to clot and help to control bleeding.
