I am most ashamed of inadvertently allowing a snake to drown. My first GTP was a beautiful, semi-tame Merauke. She was impregnated by a male breeder I bought, but she had a problem with hypocalcemic shock due to shelling her eggs too early in the pregnancy. I gave her nightly warm soaks and calcium through an eye dropper, and the vet injected sub-cutaneous calcium and fluids. She was not doing well and was very weak. One night during her soak, I left the room for a few minutes...it was less than five minutes, but it was enough for her to drown. I had never expected that, but I guess she was too weak to keep her head on the rock provided in the soaking tub. I was devastated, and still feel like it's my fault she passed, but I never leave a soaking snake unattended now.
