Hello. Recently we had a huge snow storm and I didn't feed my gecko for four days. When we finally got crickets she wouldn't eat them. I usually hand feed her crickets but she just tries to climb the glass walls of her cage. I do not know what is wrong. I think she is about 9 years old. I am so sad. In one of her eyes there is a small part that looks discolored compared to her other eye. Any suggestions?
