none of my bloods are nippy and i got 1 cbb and 2 from bushmasters farms (not sure if they were wild caught or farm born) the 2 from them acted like they wanted to bite but never struck though. and i let my 4 year old hold them and he's never been bitten and my boy aint the tamest when it come to handling any animal. now 2 of the ball pythons i got bite me at least every other time i get them out of there cage (but there less then 6 months old and baby snakes always seem to bite when an adult wouldn't from fear of being eaten)
