This article describes the novel use of an Elizabethan collar, which is attached to a primate jacket to create a tamper-proof "hoop-skirt" for protecting wounds and catheters. We successfully have used this hoop-skirt to manage juvenile male rhesus monkeys with Foley catheters for 10 days post-prostatectomy. In addition, our hoop-skirt has been used to manage wounds on the hindlimbs of both macaques and baboons.
