David Dawes of Swansea said he heard a sound upstairs at his home Tuesday and thought it might be a rat, so he went up to investigate.

"When I opened the airing cupboard, I instead found what turned out to be a Taiwan beauty rat snake." Dawes said in a Facebook post he was not enthused by the RSPCA's advice. "So, I just found this fellow curled up on my boiler. RSPCA have just said to close the door and hope he finds his way out. I am decidedly unchill about this course of action," he wrote. Dawes said a friend suggested the serpent was likely an escaped pet, so he again consulted with experts and decided to attempt to capture the animal. "Following a second call to the experts, I took their revised advice; donned my thickest flannel shirt and a pair of gardening gloves, and went in to say hello," he said. "Unfortunately, my new friend was awake by now, and didn't appreciate being grabbed -- but beyond trying to scoot up the curtain, he quickly settled into a lock top box which I took downstairs."

"They quickly identified him as a Taiwan beauty rat snake, and very kindly took him in."
