A woman woke up from a nap and was horrified to find a three-foot-long snake trying to slip through her window.
When a cornsnake was about to pass through the bedroom window of a house in Basildon, Essex, a woman was awakened by an uninvited guest, closed the door behind her and fled.
She called the RSPA who came to remove the creature – had to search for it after it first disappeared.
Rookie RSPCA officer Enola Evans, who had just started animal rescues a month ago, had to search the house to find the snake.
“Snakes rarely wake up trying to get into a bedroom through a window. The woman was terribly shocked.”
She added: “By this time there were no signs of snakes in the windows, so the resident gave me permission to search her bedroom.
“But even after a thorough search of the bed linen and other hiding places in the bedroom, the snake was nowhere to be found.

“I had the window open all the time and it was getting pretty cold, so I decided to close the window and then I saw something moving.
“It was a snake coiled around the edge of the window. He hid very well, so I was really happy to find him.”

The snake, which was captured on October 8, was transferred to a carrier and taken to a specialized boarding facility for care until it could be reunited with its owner or adopted.
It turned out to be a corn snake, a non-venomous breed that people sometimes keep as pets.
Last year, the RSPCA received 1,219 reports of pet snakes needing help.
Many of these calls were during the summer months, as snakes are most active in hot weather.
