yes I tried everything popcronbird said to do, and notjhing seemed to work for me, cheeko still would bite and hiss.

One day I just took him out and then let him sit on my sholder while I mad something to eat and crud, then I went to my room "he was still sitting on my sholder" and put him on my finger. Then I gave him a mist sprey while he was on my finger. He really liked it, I do that every day now. It seems to be working.
