Talk to me about Brumation...or?!

[Clara13]

I have 2 BTS. A Northern (Mr. Skink), and my Indo, "Clara" (some of you may remember her from a previous thread, when she fell terribly ill).
Clara has been doing fantastic since her episode back in the spring. Until now. She looks remarkable, has good body mass, no apparent URI, or any other issues, but she has refused her last 3 meals (I used only her favorites), and she will not bask during the day...at all! She also has not pooped during this whole time.
Even when Clara was on her "death bed"...she was STILL eating...not kidding! She has NEVER missed a meal!
She is very cold to the touch due to lack of basking, and is generally, just very inactive these past weeks.
Is it possible she is brumating? Or is something more sinister going on? I am located in the midwest, and our temps outside have dropped substantially, but not in her enclosure. But our days are becoming shorter and shorter (i'm providing this info for the people who don't live in the states)
I assume I am going to have to vet her, but just wanted some input from anyone willing to share their advice/knowledge.

Sounds loke she may have picked up the cues outside and has decided its slow down time,my northerns do tje same,they have day time hot basking sites year round,but over cooler months the cage ambient drops and they often stay in cool zone and shut down on me,even with hot basking spot still available,its pretty hot where indos are from even in there cool period so wouldnt take much for them to pick up on outdoor cues and act accordingly if it gets cold in uour area

In last winter i checked the weather report of indonesia,and that make me think the brumation is not a natural behavior of indo...
maybe some warm bath can help?

Tropical reptiles dont generally brumate as such,they estiviate,usually the cooler season is the dry season when food is more scarce,dau temp is consistant year round,but cool period is dryer and has lower over night temps,when food is scarce,they shelter and wait it out till conditions improve so as not to waste there body fat reserves trying to find food ect

I agree.
