Hello! I was looking for some advice for my tortoise, Excalibur. He is a 2.5 year old golden greek tortoise. For the past 2 months he has been making this squeak sound. I've brought him to the vet twice now and they gave him antibiotics both times but it hasn't made a difference. The vet didnt seem to know what could be causing the sound since he isnt showing any other signs of respiratory distress. His behavior hasn't changed and he is eating how he normally does. He seems to only make the sound when he notices me or other people. I thought maybe his enclosure might be too dry so I bumped the humidity but that hasnt made a difference either. Has anyone noticed this behavior in their tortoises? Any advice would be greatly appreciated.
