I hate to say, but Cain passed less than a day after this was posted =/. I think it was kidney failure, because unfortunately the ground was frozen too much after Cain passed for me to bury him right away, and I didn't have any real storage place for him. He sat in the pet carrier on paper towels until it was warm enough for me to dig. During that time, a spot developed on his back, right where his kidneys would be (I believe), leading me to think that that was decay around the kidney areas. I don't know what could have caused it, except maybe I let the water go for too long without changing it
. I was heartbroken, devastated over the loss, I had to go and get Greens from the Petsmart nearby very shortly after to fill the hole in my heart (I know not the best reason, but it was a rough coming week and my first beloved frogs passing was not something that helped). I plan on getting a new tank and another pair of Grays over the summer though, seeing as how they like to use my pool for their tadpoles. Provided they come back this year that is.
