I've had my Ball, Lucie, for about 2 months now. During that time she's eaten nearly ever week. The only times she hasn't has been the very first week that we had her, and the other was when she was in shed. Other than that, no problems. She's been eating F/T fuzzy rats. When I got her from the breeder he had said she was eating live fuzzies, but should take to frozen with little to no issue, and she has.
I last fed her 3 days ago (Friday the 17th). However in the days leading up to being fed and everyday since, she's been pretty lethargic. I just assumed that it had to due with her having just ate. Also, been having trouble with humidity here very recently. Nothing drastic, just been having trouble getting humidity to stay up, kinda out of nowhere. Didn't used to have this problem. Anyway, on top of being lethargic, when I reached in her cage earlier today to refresh her water and she snapped at me. Something she's never done before. Like I said, she JUST ate. So I'll if she's uncomfortable due with the problem with the humidity or if she's still hungry.

If she's still hungry, can I feed he two fuzzies or move up to a small rat?
