:rofl: Guys cut me some slack, i'm a busy man. This is what happened. The gecko was still pooping but uncle said he thought he saw a trace of blood. Took him to a vet, no parasites in stool, they did an exray and some abnormality and the vet said it would to best to a study using barium. The vet could see there was a problem with a part of the intestine, some of the barium did not enter the part of the intestine. Blood was taken and showed infection and he put the gecko on antibiotics but said he needed surgery right away. It turns out he had developed a obstipation from the substrate and part of the gut had died. The vets plan was to cut that portion out but in the middle of the procedure the geckos heart stopped. They did a necropsy since he was already there and they found nothing else wrong with the gecko. I'm not talking bs, I have better things to do. I seen things like this all the time years ago when I worked at a vet office. How many herps die and nobody knows of what? There is alot of issues with substrate. Abrasions from wood and some are toxic like mulch that can let out phenols and some come with mites. We had herps come in with fungal infection, ulcerative stomatits, all kinds of infections and parasites. Some will reinfect themselves by ingesting the dirty substrate. Some get prolapse from substrate being sucked up while pooping. Unless you have a natural vivarium with all kinds of critters like springtails, something is bound to go wrong one day.
