see i did feed in the tank then my little odakota diddnt hit his mouse just right and got a mouth fuul of substrait and he couldnt get it out i had to pic him up and pic all the peaces out of his mout cuz i heard that if he swallow his bedding it can hurt him so now i just put him in a big plastic tub with a hide box and paper lined bottom also he seems to get exited when i puul out that tub at feeding time
