I don't know about it being a regulation. It may be an insurance risk having an "Exotic pet" in a home based elderly care location. Even if your mom just wants the snake gone..It's going to suck and it going to hurt and its not going to be easy..But the mature thing is to respect her wishes and find a new home for your pet. I know that not what you wanted to hear but I may be the reality at this point in your life..

Good luck with what ever you descide .
