    Hey, I’m pretty sure my almost 2 year old crested gecko has mouth rot. She’s lost her appetite and she has small cuts around her mouth. She’s twitching randomly and is displaying signs of discomfort such as opening
    her mouth wide and turning her neck in a concerning way. I don’t have any antibiotics for her and don’t know what antibiotics are OK for her to consume. Please send me info on how to treat this sickness.
