Should I feed

When I got up this morning both my temperatures were 3 degrees below normal. I accidently left the window open. But today is supposed to be the 1st feeding day. The temps have returned to normal now, but should I try to feed or wait till this weekend

If your snake has been with you for at least a week, and seems to have settled in, I think it would be fine to offer prey now. If she wants to eat, she will take it. If not, wait another week or so ;)
