Sorry to hear about Spyro. What have you been feeding him lately? How often have you been bathing him? And if you have a thermometer, what are the temps on his basking spot?
His basking spot is always usually between 100 - 110F and he has been eating more
veggies lately and he ate some tomato the day before yesterday, it didn't smell good but it was just the way it always smells
If I were to guess, which is what I am doing I would say it could be from the tomato.
Beautifuldragons.com has a wonderful food list, if your not using it, you should be, it is excellent information.
Let us know how her poo is today.
