Chronic cannulation for intermittent intravenous fluid administration

A system is described for rapid and effective venous cannulation for long-term administration of fluids in rabbits. This method is completely free of any harness or sling-type apparatus and in no way interferes with the normal mobility of the animal. The animals maintained in this way have participated in programs of tri-weekly administration (2–3 ml/dose) of fluid for as long as 5 mo.
