Racers are one of the few snakes that are sight hunters. That is why when you observe them out in the wild hunting, you will see them with their head held high above the grass. They key in on movement, and if it is something that they can eat, its lunch. Racers are not constrictors, so they do not normally eat larger mice or snakes. However they will eat juvenile mice, any lizard, small snakes, and, believe it or not, cicadas. They will gorge themselves on these when they are emerging.
But as far as yours, if you can get it to eat small live pinky mice, it will do fine. You may have to put it in a deli cup with a pinky and leave it for a few hours or even overnight.
But if you cant get it to eat in a couple of weeks, then it would be better off to release it. You could try small lizards, and if it eats one, drop in a live pink and see if it will eat it as well.
I have an eastern yellow belly racer that is doing great on F/T mice.
>>Thanks for your help. I did some googling on it, and found a description of a young black racer. It's already bitten me twice! Haha.. I expected that though. I'm keeping it. Any ideas on what I should feed it? So far I've read that they eat pretty much anything from fish to insects to other snakes!

>>Anyone know the life span of the Racer?
