I can’t think of anything that would account for the dark color. They have had beet greens, watermelon, carrot tops, and bell peppers. That’s about it. Other than they, maybe they got ahold of some weeds that I didn’t catch in time?
I can go out and try to get a picture. But it was into pine shavings, so I might have to wait until I can catch her again and it might be a little difficult. There are dandelions in the run that they snack on, id have to smell it when she puked again to see how it smelled. She isn’t behaving odd. No lethargy, no other symptoms that you mentioned. She ran straight to me when I gave the watermelon. No fireplace ashes, no berries etc.
