Hopefully getting a reptile room this year. We will have a security system for the house and I'll keep the door to the room locked. I wouldn't invite people over to my place for sales. That's just weird to me. I don't want them to know exactly where I live and especially not the layout of the house. If someone local wanted to see in person I'd meet them somewhere public.
I don't really get the whole point of someone coming over and interacting with the snake before purchasing, especially with ball pythons. I buy for genes and the quality of those genes. I can see that with online pictures. Aside from the boa, every snake I've bought is from seeing one picture and I was never displeased or misrepresented when I got the snake in hand.
I've read too many stories since joining this hobby about theft, and I plan to be extra cautious about it. It makes me really uncomfortable when my roommates have parties. I go lock the T8 doors. I also don't like answering their questions of how much they are/how much I've spent. I trust my roommates and their close friends but not random party people. I like the fact that non snake people don't just how expensive these animals can be.
