Hello again, everyone!
So... I'm writing today because I have a few questions/concerns for all of you. I've had my new little white's for about a week now and I've noticed some strange behavior. She's eating just fine - like a champ I might add! She's always super interested in what I'm doing when I hold her (which isn't too often, I swear! I mostly sit her down and let her do her thing and she walks around, et cetera. I'm careful about what surfaces she's on and all of that). But here are some of the pros and cons of her behavior I've noticed:
Pros:
-She eats really well. She eats 1 or 2 crickets a day (small ones).
-She reacts well to stimuli. Crickets, my hand in the terrarium, light, et cetera.
-She climbs well. Good muscle strength and movement.
-She pees and poos a lot! I've read that this is a good - and healthy!
Cons:
-She seems to HATE her water dish. I'm using the right, clean water for her dish and spray bottle to keep the humidity/moisture up.
-Her skin tone seems to change from a bright green to a dark green sometimes. I understand that this means she's stressed?
-She doesn't seem to ever really sleep. Whenever I look at her during the day she has her eyes about half open - like she's trying to sleep but can't? Is this normally how their eyes look? I assume she is active when I sleep (I'm usually up really late though and don't see her moving much). But if there is food in her terrarium it'll usually be gone by morning? But it appears she never left her perch spot?
-She's very lethargic. During the night - like right now - she just... sits there at the top of her terrarium on a perch I set up for her. She RARELY comes down from the perch. She has no interest in any other areas of her terrarium - besides maybe the closest point to the top by the light.
Thank you guys for all your help so far! I'll answer everything honestly and as effectively as I can. I just hope if I'm not doing something right that you guys won't judge me!

I'm new to this - trying to learn all I can. Also, she does have a vet appointment coming up soon!
