I read that a crusting around the eyes of a tortoise (Sulcata), is a sign of a repsiratory infection. Well, today I got home from work and went to check on Sully... and shim's little eye had what looked like dead skin or something on it. I tried gently removing the substance, but I had no luck. it is very light, almost white. It is only evident on one eye. I tried to get a picture... but it isn't clear enough to tell. I am just concerned... I don't want shim to get hurt. My tortoise has still been eating very well, is decently active, and is still responsive when I attempt to remove shim from the cage. Just some dirt or should I keep a closer eye on him?
Thanks!
