They can become accostumed to you if they are healthy but they won't sit on your lap like lap dog or grr feed from your mouth. The person on the net who is teaching people that it's ok to house train them actually killed her's in less then two years ,drowned a few and needed to "break" hers in. Of course putting a leash on them so they can roam for a bit outside thier cage in my opinion is ok as long as it's not for a long time(say +3 hours unless the outside temps are hot and humid) and you read your pet's cues,like if it hisses or becomes agressive, also never take a hiding sav out of it's "safe" spot. Of course some of the sav training out there is rediculous. Paper training is honestly a waist of time as you should't have them out that long and it's stressfull, letting them sleep with you also stupid and the most idiotic thing yet is to let young kids climb on, try to kiss, and feed a sav while out of the enclosure. that's just calling for the monitor to hurt your kid as they are still considered "wild" even if they come when called!!
