There are more tigers in captivity in Texas than there are in the wild in the rest of the world.
Same for the Blackbuck antelope.
It is really quite amazing what animals are out there.
Many years ago I worked as a metal building construction/weldor.
The Boss often times picked up extra work on ranches around south Texas repairing gates, cattle guards, etc.
On one job out at a ranch south of San Antonio we had to repair some very heavy duty fencing made from 2" pipe. The rancher had a frickin rhino inside the enclosure. The beastie would come over while we were working on the fence. It never acted aggressive. The owner showed us how to feed it cabbages. LOL.
I always thought how cool is that but I sure didn't want to get too close to that thing.
