Do crested gecko lizards hibernate

No. Were they come from they do not need toThey do, some people "hibernate them" when they want to breed them.If it is a pet in a temperate climate it may "slow down" eat less and be out less in the fall and winter, that is OK. Be concerned if it is not eating at all and getting thin. Talk to someone that specializes in reptiles (most locally-owed pet stores that sell them)if it gets too thin.
