It's not a garter but it brings the point home about not leaving live pray in with a snake. This Fox snake lost both its eye because the owner left the mouse in with the snake and didn't monitor the fed. This snake was brought to me today and will live out its life here on the Ranch.
I must admitt I too am captivated by constrictors when they feed. When I've had Bull snakes on the Ranch I have always fed them live mice. The person responsible for this injury could have avoided it if F/T were used. Seeing this snake brings home the reality of what live pray can do if not monitored.
