My ball python died. What caused the black spot on its belly?

Updated on September 23rd, 2025

My ball python passed away some time last night and I'd like to better understand the reason based on my findings. He had fresh clean water, his tank was cleaned about a month or so prior, and temperatures were correct with both a warm and cool side. He ate a F/T large mouse of the correct size Sunday night and at that time displayed no symptoms. After death his normally all light tan underbelly had a 4" black area about 3" from his anus. I obviously suspect food poisoning of some kind.

Thanks for reaching out about your ball python and am sorry for your loss. I suspect the dark area was feces in the colon observed through the skin. If the body was refrigerated, a veterinary can probably perform a necropsy with the hopes of providing some answers.
Good luck.
