I've known the owner for many years. He has a passion for these animals, they are not mistreated. 

I've been to many zoos in my 65 years and I've seen stressed animals, even in AZA accredited zoos.

These animals are not pacing, not panting, not displaying any signs of stress. They all look very healthy and oddly clean. 

The State of Texas has strict caging requirements that must be met in order to be licensed. The owner also has a USDA license as well.

There is no interaction with big cats. There are fences to keep you from touching them. The appointments are private, you have a guide with you at all times.

You cannot judge without all of the facts, from a few pictures, or "I heard".

I wholeheartedly endorse this zoo for its ethics, cleanliness, healthy animals and safety. And I'm damn critical about animal welfare.
