I have just joined your group & would like some advice on my Female Tortoise of about 50 years old, who is eating well & appears healthy. But, yesterday I noticed that she has developed a white spot in both eyes & her muck was white & hard. She produced urine with the usual white content like the skin off milk. But, her Poo is usually black or Dark Green was white, like chalk, very long & a section of it was quite big & rubber like! I've never seen anything like this from her before. She is eating well & the only thing that she has eaten a lot of in the last few days is Spinach. Has anybody experienced this... not personally, I hasten to add!
