So my little sister has Asperger's Syndrome (a form of autism) and recently we went to a zoo and one of the keepers was doing a talk and had some slithery assistants. She let some of the kids pet the python she was holding, including my sister, who liked the smooth feeling of its scales. I've been doing a ton of research lately about getting one for her but I can't decide which species to get. I would be the snake's primary carer of course (I'm doing an Animal Studies course at TAFE). Any insight would be super helpful.
