What is Elizabethan Collar?
1.
A collar that is conical in shape, increasing in radius as it goes over the head, used to prevent animals from irritating wounds due to surgery or injury. Also tends to be the butt-end of many a joke, as its appearance can be tremendously comical in nature, especially when fitted to a domesticated cat.
