This was quite an opportunity I had, to watch this snow leopard play (through the glass) with a gentleman who has visited him regularly, since shortly after he was born.
I watched him sneak around as if to attack the man as he was walking toward the viewing booth.
Once he got there he batted the window with his hands then the leopard stood up and batted back non stop.
The two did this for the longest while and when the man walked away, the leopard acted so sad to see him go and followed as far as he could.

I caught up with the fellow to get more information...fascinating to hear about all the adventures he has here at the zoo, with a number of animals he has gotten to know.
He took me around to a few of his favourites, giving me such wonderful side notes I would have otherwise have missed. I'll try to post a picture of the man soon.

A closer face shot of this beautiful leopard in next photo. Though not the greatest shots, it was exhilarating to watch.:o)
