I agree that you might think about raising the temps to just below 90 on the warm side. Most kings have a really good appetite. It is good that you are keeping an eye on her weight and it's good that you've come for advice. You might think about grabbing a fecal sample less than 24 hrs old and taking it to a vet to get a float done. It is possible that she could have parasites. Keep us updated.

by the way, she's a cutie!
That is awesome, I didn't even think about parasites. Ill be sure to stick her on paper towels so I can easily grab a fecal sample. Thank you!!
