My female veiled chameleon suddenly became weak and not very active yesterday afternoon. She has been trying to climb up to the branches in her enclosure but can’t seem to get a good grip and falls. Her eyes look dark and sunken in and she hasn’t been eating. I feel so shocked because she has been so good and active these past 5 months that I have had her. She looks pretty normal and healthy besides her eyes looking sad and dark. I don’t know what i’ve been doing wrong for her to get like this so suddenly.
