Monty (our ball) has taken to us so much! When my youngest son says good night to him/her, s/he yawns! Every night! We have only had him/her for less than a month! They are so cool to have. Monty (to me) does not act like a normal ball either.... s/he LOVES to be held and interact with us.
Same with ours. He puts up a pretty good fight when its time to go back into his tank. also seems to get a little disgruntled after feeding when he gets "neglected" for a couple of days.
