  • The anal sacs are two small pouches located on either side of the anus at approximately the four o'clock and eight o'clock positions. The walls of the sac produce a foul smelling fluid which is released whenever the 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 (for several days until the swelling and inflammation have subsided. If a cat has several episodes of anal sac disease, and diet or supplements do not relieve the problem, the anal sacs can be removed surgically.

  • The anal sacs are two small pouches located on either side of the anus at approximately the four o'clock and eight o'clock positions. The walls of the sac produce a foul smelling fluid which is released whenever the dog passes a bowel movement. Bacteria that are normally present in the feces can readily travel up the ducts and enter the sacs resulting in infection. The first sign is often scooting or dragging the rear along the ground. Treatment for impaction involves expressing or emptying the sacs. Antibiotics are often prescribed. Most dogs will require pain relief medications for several days until the swelling and inflammation have subsided. In recurrent or severe cases, surgical removal of the sacs may be necessary.

  • An anaphylactic reaction or anaphylaxis is an immediate hypersensitivity reaction to a foreign substance, especially a foreign protein. Any foreign substance can produce an anaphylactic reaction. Clinical signs are dependent on the route of exposure (mouth, skin, inhalation, injection, etc.), the amount of antigen and the level of the pet's IgE response. An anaphylactic reaction is a medical emergency and immediate treatment is required.

  • Anemia is a medical term referring to a reduced number of circulating red blood cells (RBC's), hemoglobin (Hb), or both. It is not a specific disease but rather it is the result of some other disease process or condition.

  • In cats, the pupil is an elliptically-shaped opening in the middle of the iris that allows light to pass through the eye to the retina. The pupil constricts or dilates (enlarges) according to the amount of light that enters the eyes, with both pupils normally dilating in dim light and constricting in bright light.
