Content
The clip starts with footage of a man feeding some snakes at the shelter. Eventually, one of the snakes starts getting a little too tough to handle as it keeps missing the mouse that's being offered. Then, the snake accidentally falls from its confinement and onto the floor. Taking action, the man places the mouse in the confinement before putting the snake back successfully. However, when the man opens another shelf to check on the next snake, a stock snake head zooms from the center and hisses loudly.
