Officials tell KHOU-TV the tiger was well fed, but the cage was secured by a nylon strap and screwdriver. Officials say it could easily open and the tiger could have gone on a "rampage." The tiger was taken to an animal shelter, then it was transferred to an animal sanctuary in Texas on Tuesday.
It's legal to own a tiger in Texas if the owner has a wild game permit. But it is illegal to have a tiger in Houston.
