Rhea,
When you say you prefer not to keep garters solitary is this based on the fact that garters seem to need a social situation? or is it based on limited cage space? Do you keep only same sexes together or does it not really matter? Does this seem to affect the way a WC garter tames down? if so, does it help them acclimate to handling and being a pet or does it take longer when they are with another snake on a regular basis?
