Javas are very intelligent. Understand simple commands. They stay wonderfully tame (with their handfeeder), for life, if done correctly like this gentleman here. I have 2 (male female) that are about 4 years. Absolute best for a committed fincher who understands it is a 6-10 year commitment with the strong bond. They never react quite the same with a new "owner". I would never give up my hand tamed. Bond is real. Nice work, who ever made this video.
