Veterinary Anesthesia is anesthesia executed on non-human animals by a veterinarian or a Registered Veterinary Specialist. Anesthesia is used for a wider range of situations in animals than in people, due to animals' lack of ability to cooperate with certain analytic or therapeutic procedures. Veterinary anesthesia consist of anesthesia of the major species: dogs, cats, horses, cattle, sheep, goats, and pigs, as well as all other animals requiring veterinary care such as birds, pocket pets, and wildlife Hostile animals may require anesthesia in order to handle and perform a physical exam or obtain blood for analysis. Striking animals frequently require anesthesia for simple procedures (such as taking a radiograph or catheter placement) due to lack of domesticity. Animals may require anesthesia for therapeutic procedures, such as urinary catheterization to relieve obstacle, injection into a mass, or removing liquid from the eye to treat glaucoma.
