Just caught up with your thread. Sorry to hear that Zylvan taming hasn't been going as well as you would like, but it's good to read that he is regaining his confident and has started taking treats through the mesh again. He may just need a little more time to feel confident with your hand before accepting treats not through the mesh - my Toffee was terrified of my hand at the beginning and wouldn't take treats from be but hide away but with a little time she soon found some inner confidence - taming slowly started to progress. I found with her that the smell of fresh veg was to hard to resist.
If you feel that it is best to adjust the cage will help with taming then it may be worth a try.
Try to remain positive as I know you will be able to tame him.
