Texas has very few laws regarding animals - but the counties sometimes do. In fact, (and I know I'll be slammed for this), they should have more laws. There was a tiger found shot on the side of the highway not too long ago - declawed. Someones 'pet' who got to big. I work with a gentleman at an outdoor center - the number of 'legal' animals he has is outstanding. Animals that are released into the wild where, in Texas, they can survive quite nicely - interfering with native species. House geckos are wiping out the horny toads.
These were sold as pets. (I researched to make sure gliders could not survive outside through the winter in my area before I got them - just in case.)
People have foxes, large cats, bobcats as pets. In the outdoor center they have a - full grown chimp (kept in a house), a bobcat - declawed, gliders, hamsters, a red fox, iguanas (I think all legal in Texas) as well as a few illegal animals - either locally or statewide such as owls and hawks kept for pets.
I do believe in the freedom of pet choices, but not when those animals are dangerous to the native environment. (Or when it just obviously should not be a pet, like a tiger!)
