Snake: Hybrid Pine/Bull snake
Age: 2-5 years. I'll update when I find out for sure.
Length: 4ish feet
Weight: 650 grams
Appetite: eats 5-6 f/t mice every 2 weeks. Has been known to eat as many as 9(small to medium mice) in one eating session(total garbage can). Recently has been upgraded in mouse size and is a voracious eater.
Attitude: can be extremely hissy but is a very gentle snake
Issue: Seems weak and very skinny(triangular shape and shows prominent spine)

Background/concerns: This is a snake which I have known almost 2 months. It is 1 of 8 snakes I help care for at the nature center which I volunteer. This snake was skinny and lethargic from the start. After getting her helpings up from 2-3 small/medium mice every 2 weeks to the current 5-6 large mice every 2 weeks, she has improved in strength. On Wednesday there was a regurge of half her meal(3 mice) in her enclosure. I think it may be from inconsistent temperatures at the nature center. Outside of feeling a little weaker and less of a hissy attitude, she seems "ok". I brought her home to my place(quarantined) so she can receive better/consistent/more observant care and heat. At this point I have mixed some pedialyte in with her water to keep her fluids up and am debating a pedialyte treatment every 2 days for a week. I am going to monitor her weight over time to see if it fluctuates. My guess is she is almost empty at this point as she defecated this week with the regurge. Gut feeling tells me the regurge is an isolated incident and is do to temperature issues or possibly 1 bad mouse. I'm more concerned with her being skinny and weak. I have asked a friend to see if her vet would be willing to see the snake at no charge. I am concerned for the snake but not to the point where it's gonna die in the next week.

My thought for possible ailment: internal parasite

I'm looking for thoughts on possible ailments for why she is skinny and has kept almost fine and dandy attitude.

Here is a pic of the snake and the enclosure. The nature center uses unprinted newspaper as a substrate, I have her on aspen with a new hide and water bowl.
