  • 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.

  • Antioxidants are given by mouth and are over the counter supplements used to treat side effects from inflammation. Give as directed by your veterinarian. Side effects are uncommon but may include mild stomach upset. Use antioxidants cautiously in pregnant pets. If a negative reaction occurs, please call your veterinary office.

  • Aortic stenosis is a heart disease that is present at birth. Cats affected with aortic stenosis have a narrowing at the aortic valve of the heart. The clinical signs of aortic stenosis vary depending on how severe the stenosis is; some cats remain asymptomatic throughout their life, while other cats begin showing clinical signs at an early age and can experience sudden death. The treatment of aortic stenosis depends upon the severity of the condition.

  • An aortic thromboembolism (ATE) results when a blood clot is dislodged and travels through the aorta, becoming lodged in a distant location. This clot causes severely reduced blood flow to the tissues receiving blood from that section of the aorta, leading to decreased oxygen in the tissues. A heart condition called hypertrophic cardiomyopathy is the most common cause. This article outlines clinical signs, treatment, monitoring, and prognosis for cats with this condition.
