Play, play and play! Figure out what he likes - whether it is chasing a ball - a wadded up ball of paper will do, nothing fancy, or chasing a feather on a string, or what kinds of toys he will play with. If he starts to bite human or furniture, have a toy handy to substitute instead. He will "get it" eventually - and of course as the saying goes, a tired kitten is a well-behaved kitten!

My favorite suggestion for tiring out a kitten - ping-pong ball or two tossed into an empty bathtub - the curved sides keep it moving back toward him when he bats at it!
