So I've had my Boa for 7 months now, and nothing about his environment has changed since I got him (except I added some stones and an additional grapevine to his enclosure one month ago) and that didn't trigger this behavior. His temperature has been consistent, 78 on the cool side and 85 on the warm with a hot spot of 89-90, humidity hovers 60-65 when not in shed and 70-75 when in shed, he's shed twice with me both perfect sheds, he gets fed once every ten days, and he lives in a 48x24x18 pvc cage with sliding glass doors and a water bowl large enough for him to soak if he needs, a hide on both warm and cool sides. And he's on coconut fiber for a substrate.

his husbandry has never changed in the 7 months he's lived with me.

now one thing that has changed two weeks ago was I brought home a ball python, he's in an enclosure opposite to my boa so I'm sure they could probably see and smell each other 15 feet apart.

could this cause my Boa to constantly be stuffing his nose in the crack between the sliding doors at night?

as an additional note he's 2'11" just over a year old and weighs 284 grams.
