I have a year and a half old boa constrictor and some people suggest the more you handle it, the shorter the snakes life span? I know snakes don't like handling they just tolerate it.. But will my snake really have a shorter life? I handle him once maybe twice a day (apart from after feeding and when he's in shed ECT.) and only 10-15 minutes at a time.. Is this ok or should I be handeling him much less? He's very tame and never bitten, will he get agressive if I handled him less?
