I agree with most of what Gio says other than the handling part. That really depends on the snake. My BP likes to be left alone for the most part. Once she is out, she is content being on me for about 15-20 mins, then she wants to explore or go hide under a pillow or blankets. My boas are a different story. Rosey loves to come out. She will windshield wipe the cage front until I open the door and then she comes out, flicks the tongue at me and climbs onto my arm and up to my shoulders and sits there. Vicky is the same but not as often as Rosey. Rosey is a very social snake and loves to be out and sit on me. You have to just learn how to read your snake and each one will have their own personality. I usually handle Rosey every other day. Vicky usually every 2-3 days and Dottie one to two times a week or whenever she comes out at night and starts exploring all over.
As for feeding during winter, I have always just fed them normally through winter. Dottie gets a rat every 2 weeks, Vicky gets one every 2-3 weeks and Rosey gets a rabbit every 3 weeks to 1 month. Anything over a month and Rosey tears down her rhp wire, the light wire, pushes aspen into piles, shoves her water bowl and hide around and pushes on the corner of the cages and overall gets agitated lol. Hopefully this changes in about a month and a half when all my AP cages get here. Went with the built in LED lights and heat tape so I don't have to deal with any wiring inside the cage at all.
