I agree. When I tell people that I have a pet python, no matter whether I say python or ball python, people do not know what that means... most automatically assume it is a massive Burmese python that is 26 feet long. They always nod and ask 'and how long will it get to be?' and when I tell them its a male ball python, and what its max growth is, they look confused and usually say something like, 'Oh I thought they got to be much larger."
IF it helps - you can get renter's insurance. That usually covers pet damage and can help you land an apartment. I think its about $35 a year? Maybe $50?
I agree. The movie anaconda is what seems to come to mind first... that and confusion with the Burmese pythons that get to be BIG.
