Thanks for the quick replies. As for the humidity, yeah I think her dial broke last week. It was reading 70% though I can only imagine it isn't at that since she had a bad shed. It came off all in one piece except for the tip of the tail which is hanging on. I am going this weekend to buy a new (and better) humidity gauge for her. Our other ball's cage has a much better temp/humidity reader, so I am probably going to go and buy that one as he never has shedding issues.
As for the weight, she hasn't lost, somehow, but hasn't gained either. Our other guy is growing like a weed. She used to be the "big one", and now the size difference is amazing. Hopefully we can get her on a better pattern soon. She has really come out of her shell in the past few months (she is much more shy than the big guy), so I'm hoping better feeding is soon to follow.
I'll check for rats for the big guy. The reason I didn't try them yet is when I went to the reptile show, they said for his size rats were inappropriate and the extra large adult mice were the way to go. We feed him every weekend, and after one "appropriately sized mouse" (according to the keepers there), he is still starving. I feel so bad for the poor thing I give him another, but if that's not safe I'll definitely stop.
And I really need to come up with names and stop calling them "he" and "she". I tried to name the little one Snickers but the hubby was not having it.
