I have had my 1.5 y/o snake since December with no problems feeding 1/week. Last feeding she refused for the first time, just didn't seem interested. The store said she is a female, but maybe they were wrong and he is going through his winter fast. Or maybe she is getting ready to shed. Her skin seems the same though and her eyes aren't cloudy. I tried to feed her again today (3 days after last try) and no luck. My question is how often should I offer her a mouse? Once a week? And is there any way to save and reuse the refused mouse? I threw away the last two, but if it is OK to refrigerate/refreeze, please let me know. Thanks.
