Wow long thread. I read as much as I could before posting.

I have to echo everyone who said you are 27 and live in your own home so grow a spine.

I also agree that you should not take your newly stiffened spine and beat your mother over the head with it.

You and your mom have to both work on your dynamic. So here is my advice. You can not change anyone except yourself. You can choose your actions, words and thoughts.

Here are some mom comments I made up and some responses you could give that are respectful but assertive.

MOM:"you have to get rid of them I can't stand it anymore!!"
YOU:"Mom I love you dearly and I understand that my snakes bother you but I have to live my life how I choose, I don't have to get rid of my snakes. I know that YOU can't stand them and you WANT me to get rid of them, but I love them and they make me happy."

MOM:"So you are choosing the snakes over your mother!"
YOU:"I am choosing to keep the snakes and you in my life, are you choosing to cut your child out of your life because of a small animal no more dangerous than a cat"

MOM:"Well I am never comming to your house again."
YOU:"I can't tell you how sad that makes me that you don't feel comfortable comming to my home. Is there anything I can do to make you feel safe in my home other than get rid of the snakes?"

MOM:"Mark my words the snakes are going to hurt you and then you will know I was right all along"
YOU:"The snakes are animals and they could bite me, but they are small animals with little itty bitty teeth. I have more of a chance of getting hurt by a cat or dog. Regardless its a risk that I choose."

Hopefully you can work things out but in the end I don't think this has anything to do with the snakes really. It sounds to me like the snakes are just one example of a bigger problem.

My mom is not a big fan of my BP, but our dynamic is much different than yours and your moms.

My MOM:"Ewe, I don't know how you live with that thing in your house"
Me:"I know its awful, I have to feed it once a week, I have to make time to change the water every couple days. Do you know I even have to take poop out of the cage every couple weeks, its hell. Get this sometimes, not often but sometimes I even see the snake come out from under that plastic hide. Its crazy, she will just slither out like she is going to look around or something. Speaking of nasty filthy animals, how is that dog of yours that pees all over the house. Is that cat scratch on your arm healing up ok."

You made your mothers life miserable now its her turn to make yours just as fun.
