My 14 month old snow has partially regurged her last two feeds. She's was slow to take both times, but managed them no bother, and they're certainly not too big for her. This time there is part regurg, part poop. Should I be concerned? Read some comments here about leaving her now for 10-14 days before trying again, and then trying with something smaller, so will try that. She lives alone and otherwise seems perfectly normal, although her substrate is a bit of a mess - she's burrowing and running around for snakeworld!
have you checked the temps. as you have said leave for 10 or so days. what are you feeding her. mave you change your supply of mice or noticed they are of bad quality.
Temps are good and yes I have changed supplier recently, but my 10 month old motley takes them (big fluffy / small mouse) no trouble, so not sure it's the mice. Pandora (the snow)has turned her nose up at them - actually recoiled when sniffing them - before taking 5 mins later. Needing some more supplies anyway so will go back to the old place, just in case.
