9 month old sand boa refuses to eat!

[bluewind]

My first post is gonna be a doozy yall!

I wish yall had an illness forum that I could post this in. Hopefully the right people will see it and can help. Long story short, I have a sweet little sand boa named Carrot who is not doing so well. We bought frozen mice from a local pet store instead of a chain store. The man told us she was ready for hoppers (she was eating 2 fuzzies per week), so we did as he said. Carrot had a lot of trouble with it and hasn't eaten since. We took her to the vet after a month to find she hadn't digested it. Another month has passed and we have done everything the vet said with no results. We raised the cage temp, cleaned it, offered only pinkies, brained feeders, cleaned the feeding box, soaked her daily, and offered food in cage. The vet gave her mineral oil and an enima to get the mouse out of her, oral liquids and vitamins, and a steroid shot.

She has been a lot more relaxed since we moved Lily (our female albino sand boa) in with her and has quit trying to get out of her cage (something that started two weeks after she stopped eating). They are very close and like to be near one another (something that sincerely surprised us both!). Also, they were both professionally sexed as female and Lily is only about 4 or 5 months, so they have plenty of room for now.

Reptile's Info: Kenyn Sand Boa, female, and about 9 months. We got her about February or March from PetSmart. Her tankmate is Lily, a 4-5 month old female albino sand boa. She never refused food until now.

Handling: We handle them both every day save on feeding day and the day after that for digestion. They are both very social and get upset if they go without being held for long. They love their backs stroked and their chins scratched. They are very passive and had fun being passed around the vet's office from nurse to nurse. Carrot isn't to fond of the vet for obvious reasons, but shows no aggression and mostly just tries to crawl back to us (or a nurse) when the vet has her. Niether have ever bit or tried to bite anyone since we have had them.

Feeding: Carrot was eating 2 frozen fuzzy mice every Sunday. They were thawed in room temp water and put in warm water right before feeding. We use filtered water (my dad has a well fed from a spring, so we use his instead of ours. It's extremely clean, but we filter it anyway to be safe). She is put in a critter keeper with a washcloth and a small under tank heating pad underneath that takes up 1/3rd of the critter keeper. She is not held that day and taken directly from her tank to the critter keeper. We dry the mouse well using a paper towel and use long feeding tongs. The trouble started when we fed her a hopper rat (they we're the same size as a hopper mouse because they were miniature) we got from a non-chain store during a mouse recall. She had trouble with it and hasn't eaten since. She's lost a lot of weight, but has shed once and is about to again (they are still young, so they shed about once a month). She is normally ravenous the day after a shed. We occasionally use a calcium spray on the mice. We tried to add vitamin drops to the water, but she refused to drink it.

Hydration: We have a water dish that has a gradient from shallow to deep. We use filtered spring water changed every day to every other day. Before she became sick, she got a soak once a week (she loves them). Now it's every day to every other day. She always drinks the water during. We mist daily until the aspen is not dry, but not sticking to fingers. The hydrometer reads 20-50%. During shedding, we increase it.

Feces: Black. She went an entire month without a bm. After enima, she produced white feces with yellow urea. The vet has not tested for parasites, but will be the next visit.

Symptoms: Not eating for 2 months, not pooping for a month, and weight loss of nearly 20 grams (according to vet scale). She has no bad smell, leakage, wounds, discharge, breathing issues, skin discoloration, or swelling. The only remotely odd thing (other than obvious) is I have witnessed her sneeze on a couple of occasions.

Cage Info: 20 gallon glass cage with locking screen top. Under tank heater with rhenostat in tank to control temp. It is located in our bedroom away from air vents and fans. It's low traffic and quiet with no tv or electronics to make noise. Small amount of natural light from windows on the opposite side of the room. The top of the cage is about 4 feet above the floor.

Temperature: Warm spot was max 95 degrees Fahrenheit and as low as 92. Vet had us increase it to 98. Cool spot is about 80 under aspen. Climbing tree for temp down to 75 if they need it. Temps are measured using a rhenostat and a digital reptile terrarium thermometer/hydrometer.

Geographical Location - USDA Hardiness Zone 8a, Köppen Climate Classification of humid subtropical climate, and elevation of 300-400 feet above sea level.
