Ooo. That right eye doesn't look good at all! Not only is it very puffy below the eyelid, but the pupil is smaller and appears misshapened. I hope someone can post a more recent photo of Leo soon showing improvement.
Yes, hopefully there is no disadvantage for the eye .... but in the video and the smaller pics the pupil looks better, perhaps it is only a matter of the camera and its viewing angle on the Pixtura pic .... *hope*
Leo's German name is so perfect: "Uhu". I love listening to him cluck and uhu. Any eye problem seems to have vanished. I think he was just winking at us; he was just doing his Uhu thing. What a fascinating creature. It will be interesting when Leo and Lotte start spending more time in the cave together.
