You asked in the other forum roughly the same question and I thought it would be more appropriate to answer in here. I am no expert. I have only had my first savannas for about 11 months now and my second for about 2. My larger one was owned by the lady at the “pet store” since he was a baby, wild caught. They worked with him and he liked to hiss a lot, when my boyfriend brought him home I was not happy. I used to not like reptiles. He worked with him a little bit every day. I did not touch our Loki for the first 6 months, and then I was forced to get him out of his water dish. He had been in it all night. After that I slowly started picking him up. I spend at least an hour a day with him, holding, interacting, and laying on the floor. Now he will sleep on me for hours, walks around the room when I am cleaning. He has me trained, but he does not hiss, bite, or even move when I try to pick him up or carry him around.
Now the baby, I call him Demon because that is what he is. We rescued him from someone who was not feeding him, holding him or caring for him. When we first got him he would attack me when ever I tried to get in his cage. When I would pick him up he would bite me, so now I use a glove, I have yet to be bitten on skin and plan to keep it that way. After talking with some of the guys in here it came to my attention that he may need to be fed more, so I upped his mice count and he has not bitten at me yet. Also I did not pick him up for about 2 weeks or a little longer just so he could get used to me and see that I was not out to hurt him or steal anything out of his enclosure. Last night was the first time I had picked him up; he squirmed a little at first the rested on my chest for 30 minutes, and never hissed. So I have no idea what to expect, it is just about their bath time (I let them soak and swim around then they get to run around on the floor). This will be the first time for the baby in a few weeks so I will let you know how it goes.
Just keep working with them and I would not expect anything great to happen until they are at least a year. Most people on here have their monitors to watch, which is their choice, but I love being able to interact with mine, so just do not give up, you need to work with them everyday. As the person said give him a rest for a couple of weeks, and only take him out once a day for now for a short period of time and work your way up. My Demon used to just hide himself in his substrate, now he walks around and climbs up his levels. Just give him time. Hopefully this gives you a little hope, just remeber they are wild animals, and you are a predator to them until they learn they can trust you.
