I have had them for about six weeks. I have a heat mat under half there cages set at 88 degrees with a thermostat. The room temperature usually stays around the lower 70's. I keep them in separate cages and have had those settings since ive had them with no problems until recently with just the male. It has been getting colder lately here in NE Ohio. I have been feeding them adult mice about every 5-7 days which have been what they have been eating the last few times. The snakes are getting close to the three foot mark. The weather is really messed up in northern ohio. One day it's warm, the next day it's cold. But overall it's getting into fall weather. And yeah they have been eating frozen thawed mice. I would leave them in the cage with him for several hours and he just kind of sniffs em out and leaves them alone. I have tried jiggling them sometimes but he just gets scared and rattles his tale. The female usually snatches them up no matter how they are presented.
