The concerned citizen claimed to have entered an abandoned Houston home to smoke pot and found a tiger.
So, naturally, authorities were suspicious.
The home had been abandoned for some time, Alderete said. But several packages of meat were found with the animal, KTRK reported.
Officers tranquilized the large cat, pulled it out using a wrecker and transferred it to an animal shelter.
On Tuesday morning, the tiger was taken 200 miles north to an animal sanctuary operated by animal rescue organization Fund for Animals.
"The ranch has a five-acre, naturally wooded habitat complex that emulates a native environment and that will be the tiger's new home pending a decision about permanent custody," the Humane Society said.
The case is still under investigation and it's unclear if the tiger's owner will face any charges.
