im pretty sure mine are completely thawed with my boiling water method, i time it at about 2 minutes max and thats in a baggy in the water, and when i pull the mouse it, it definitely is squishy and limp feeling, definitely not frozen. I have been feeding snake like this since I bought him a couple months ago without problem, now after his shed hes being stupid about it. but in good news, I went ahead and tried again just now and I did my usual method and he went for it and got it! he popped its guts out after constricting it, but then he couldnt figure out again which side to start from so he ended up dropping it and slithering away..

damnit why he is so dumb, this is only an 8gram mouse and he is aprox 65gram snake.
