It was good to see that the tiger was 'in custody' and perhaps she did just wander off, but the wording of what the supposed owner said sounded strange to me. I can recall driving along a road at some point, I believe in Hill Country or somewhere else near San Antonio, I believe, and seeing signs for exotic animals, as well as seeing some roaming freely within the confines of a ranch or two. I believe they had zebras and possibly giraffes. I think @Ken Anderson is correct, that Texas has looser rules for this type of thing than some others. I recall both the ripping the face off story and also the one where the stupid 'zoo keeper' let the animals loose...that really angered me.
