My leopard tortoise is making quacking sounds like a duck. It's sort of a low sound that sounds something between a duck quacking and a piece of cork being twisted out of a bottle. He does this all the time. He moves his mouth and quack quack quack several times in succession.
I have kept other tortoises and the only sound I have ever heard from a tortoise is a high pitched WHEEEE sound my sulcata made when it is scared and suddenly goes into the shell. I have never heard a tortoise quack before this. He does this at least several times a day.
He had an eye infection not too long ago, which is cured. I don't know if there is anything wrong with this quacking? He doesn't seem to have any problems like runny nose or anything and its not exactly like wheezing so I doubt it is a respiratory disease. Is this something I have to worry about?
