No, can't say I have.
I suggest posting this question in the section for the type of snake it was. If it was a corn snake, post this in the Corn Snake section, etc....
When you post it in the specific section, give more details, such as:
1) How long you had the snake
2) Size and age of snake
3) Store-bought or wild-caught mouse
4) Any recent events in the area the snake was kept in, as in; chemical use, painting, etc...
If you don't mind, let me know what section you post it in, I'd like to follow it and find out more details to see if I can help you determine the cause.
Sorry to hear about it!
Mike
