What does this mean? A long time ago I read that this indicates a protozoan infection. I cannot find where I read this. Do I remember correctly or not?
Thanks.

Not sure, but I wanted to add that I think it can occur after a snake hasn't eaten for a few months, as in brumation, then suddenly starts. Hopefully someone can shed some light on this subject.

I do know I've seen this happen with a rosy that was obviously ill. On the other hand, I've seen it occur on occasion after brumation and then not happen the rest of the active season.

I know that it has something to do with secretion of biliverdin by the liver. I just do not know if the green stools are an indication that something is wrong.

As far as I know, nothing is wrong if the snake has gone for a month or two or more without food and the gut is empty. For example, at the end of brumation or after a long fast.

If the snake has been feeding and defecating normally and the stools turn green, it may mean that something is wrong.

That makes sense. Thank you for your response.

Years ago after bringing up some brumating animals, I too, noticed the green colored uric acid crystals. I took a sample
to school and showed my biochem professor. Indeed it is a staining by the excreted biliverdin into the alimentary tract.

The lumen or inside of the intestinal tract is considered "outside" of the body since it interfaces with objects from the outside world (mostly food), hence the use of the word excretion.

Secretion stays within the body, excretion exits the body. The pancreas is considered both a endocrine and exocrine organ by
this definition.

My professor said the green uric acid was simply a higher concentration due to less water, and the sign of a slightly dehydrated animal which is typical of going through brumation. You'll also find lower post-brumation glucose levels and lower hematocrits too.

Great observation on your part and a great question too.
Just remember...all living things need water.

Thanks for your thorough response. I can now rest easily when I see the green excretion. Thanks to all three of the responders.
