Oh gosh, the poor baby
Thank you for taking her in and getting her the help and care she so desperately needs.
I also cannot believe heat rocks are even sold anymore. Or, if sold, shouldn't they have a BIG red warning on them NOT to use them on snakes ? NOT to use them without thermostats?
How can those companies even live with themselves knowing about all the misery they cause, and they have GOT to know.
They probably have some tiny "small print" somewhere on the box or instruction, knowing no-one sees it or reads it. Sigh.
