Animal welfare workers said more than two dozen living and dead animals were removed from a home after police responded to a report of a man sitting naked outside the home.
Iguanas, roosters, turtles, domesticated rats, a tarantula and four live pit bulls were among the animals pulled from the home in south Philadelphia on Tuesday, the Pennsylvania Society for the Prevention of Cruelty to Animals said.
Officers were two hours into their search of the home when they also came across a four-foot alligator.
"We started moving the junk and it started hissing," said George Bengal of the SPCA. "We thought it was a cat at first until we cleared everything away."
The naked homeowner, who had locked himself outside, was taken for a mental health evaluation, police said. His name was not released.
