I concur with devilgofer about not releasing it. It could be still "hibernating" psychologically. Adult colubrids often go off feed in anticipation of hibernation and a baby snake that has been exposed to cooler temperatures may avoid food as well. If a snake eats and is then cooled the stomach contents rot instead of digesting and the result is sickness or death for the snake. If you keep your pet at proper temperatures and it feels secure, it should start eating for you fairly quickly. Be patient, Gopher Snakes are hardy, easy to keep captives. I assume the Red racer is a Coachwhip. I would not keep these together. It is generally not advised to keep snakes in a community cage anyway, especially mixed species. A bit of theorizing here…Coachwhips eat other snakes. The constant presence and odor of a potential predator may be intimidating and stressful for your Gopher Snake. Even if the Coachwhip is too small to make a meal of the Gopher Snake, he may try (and even succeed) anyway.
