your best bet is to get it a temporary enclosure and wait till you can either CO2 is or find someone via craigslist that is willing to take it off your hands for what ever purpose.

do you have any tubs/tanks that you can put it in? throw some shredded newspaper/phonebook pages in and a little food ( cereal, pasta, left overs), some water, and it'll be set till monday.

i def would not let it go for reasons robin mentioned.
