An Elizabethan collar, commonly referred to as an E collar, pet ruff, or pet cone, serves as a protective medical device designed for animals, typically cats or dogs. Resembling a truncated cone in shape, its primary purpose is to prevent the animal from biting, licking, or scratching at its body, head, or neck during the healing process of wounds or injuries. This collar plays a crucial role in ensuring the unimpeded recovery of the animal by restricting access to the affected areas and minimizing the risk of interference with the healing process.
