Chuck Kaye, 29, of Southfield said a man mowing his yard last week alerted him that his pet was loose -- and Kaye assumed it was one of his two dogs, the Detroit Free Press reported Sunday.
"I thought my dog was getting out of the back yard, but it was actually a 5-foot, albino python," Kaye said. "I just grabbed it up by the tail and drug it back to the house and put it in a Tupperware container."
After unsuccessfully trying to find its owner through Craigslist, Kaye said he gave it to a pet shop.
"I don't do snakes," he told the Free Press. "I have two dogs, and I don't need a 5-foot snake in my house."
He said he had "absolutely no clue" how the python wound up in his yard.
"[When] I gave the snake to the pet store, they said it looked pretty beat up, like it had been outside for a while," Kaye said.
