I have a an albino checkered garter snake she is about 2 ft long and a year and a half old she is kept in a tub that is 580 mm deep and 800mm wide, which is about 30 degrees on the warm end and about 25 at the cool, lots hides provided and a large water bowl. She has always been a ferocious feeder and eats small mice but for the last 3 weeks she is completely rejecting food, she is housed with a smaller male of the same age who eats fine but I wounded if she is gravid or ill? She doesn't look particulary fat so I am unsure. She also spends a lot of time at the cool end in the water bowl. Other than that she seems perfectly happy and is fine to be handled. Any advice or ideas would be greatly appreciated! thankyou.
