Worried about Barrie

[Catherine]

This is my Barrie. My beautiful Colombian Black and White Tegu.



This picture is a few years old. Barrie doesn't look like this now.


He has lost weight and is eating poorly. His right eye looks cloudy and I doubt he can see from it. 
I actually suspect he had a stroke a week ago. He seemed off for a few days and he is not doing well now. I am really babying him, but he is an old lizard.
I think his age and the lack of good care as a younger lizard have finally caught up with him. I am going to do everything to help him and keep him comfortable,  but I don't think we have a lot of time left.
