well, i may be a bad mommy :ashamed but i don't see any problem with leaving my girl alone for a few days as long as she has adequate water and she's fed before i leave. my problem is that i change her light at night so i have to find someone to change the bulb or just leave one in, but if you don't do that then i wouldn't worry. make sure that if your heat source gets too hot it won't burn your bp though since you won't be there to monitor it.
