Those poison packs can be anywhere. Some cities put them around outside to kill rats. And also, mice can get in and out of houses. ---

Your kitty might have been able to catch the mouse because it was already sick. The more common anticoagulant poisons out there, whatever’s inside a mouse, isn’t enough to hurt your kitty. It is that kind of colour. The sack is still outside but I don’t think I have the stomach to dissect it. It seems that “something it ate” is the best answer so far. ---

Almost every morning we’d find a headless mouse at the front door. We could only assume the head was the tastiest part. One of my former cats would leave almost-dead-but-still-quivering mice in my shoes. Imagine my surprise. Even though the cat’s been gone for 10 years, I still shake out my shoes before putting them on. ---

I’ve seen what you are talking about and always assumed it was the liver. ---

livers are also one of the hugest organs. ---

I understand what you are saying. I wasn’t really inspecting it to close but to my eye it looked like the thicker round portion (lobe) of the liver had a green/emerald hue after sitting out in the air, while the flat thin portions remained liver colored. You could confuse this as the round portion being the whole organ and the other stuff just being assorted flesh. ---

Folks - this is an Australian mouse, its bound to be a bit weird. Anyway moving on…organs can change colour after cat er… death. My first thought was a liver, but maybe a kidney, or a testicle - they would be small. My anatomy experience is limited to helping dad kill, hang, and dress the occasional sheep for the dinner table a few decades ago. I have this lingering memory of blue shapes which were kidneys encased in fat after the carcass cooled. ---
