Some snakes are just "butt heads" sometimes - absolutely nothing to worry about. If you're especially concerned though, you can always offer rodents to your snakes using a pair of feeding tongs. Usually a mid-sized pair of forceps/large tweezers/hemostats will work very well for colubrids. Grasp the rodent behind the front legs with the tongs & offer it headfirst to the snake. Typically the snake will grab the rodent by the head & swallow it that way, although you may occasionally experience the snake working its way around to the hind end of the rodent no matter how it's offered.

Congrats on a successful feed!
