The range of bredli is considerably farther south than olivaceus. While day-time summer high temps are similar in both ranges, the night-time winter lows are 15 to 20 degrees cooler in Bredli's range of distribution. Night-time winter lows routinely drop into the low 40's and upper 30's in Bredli's range, with day temps coming back up into the 70's. I think they would be much more conducive to being kept outside with a good heat source than would the Olive's. Even though bredli can handle cooler temps, a good heat source would still be imperative when air temps drop below 70.
