Is it a requirement for my BP to have a consistent day/night cycle? I know it's stressful for them to have constant 24 hour light, but what about continuous dim/darkness? Or 12/12 most of the time and then a couple of days of dark?
I ask because I'm keeping my viv in a small walk-in wardrobe. When I go away for a weekend, I'd like to close the door to reduce heating costs. Should I rig up a lamp with a timer or is a couple of days in the dark OK?
