This is the second time I have seen this whitish, milky stuff. My desert Tortoise (15-20 year adult) has been out and about for a week, now. He has been grazing on St Augustine and some Bermuda, Panzies. He hasn't gone after the Hibiscus, Geranium or Marigolds, as much as I have noticed. At around two pm every day, I put out a salad of Endive, Romaine, very small amounts of chopped red bell pepper & graded carrot and all mixed with a half a handful of Zoo Med Grassland Tortoise food. I'm hoping this to be normal discharge.
