A shocked woman called the police after finding a large snake slithering through her kitchen at her home in Kew, London.
The woman put in the emergency call after finding the reptile stretched out next to her kitchen cupboards.
Officers attended the scene and managed to catch the snake and take it to a nearby vet, reports ITV News.
MPS Richmond shared an image on Twitter, appealing for anyone who might have lost their pet snake.
Reptile expert and secretary of the British Herpetological Society, Trevor Rose, said he believes the animal is a corn snake.
Speaking to the Standard, he said: "They are harmless and tactile, considered a 'beginner' level species as they are very easy to maintain, feeding on small defrosted rodents.
"This one appears to be a healthy full grown specimen, and has obviously escaped from its enclosure in the near vicinity."
According to Wikipedia, the corn snake is a North American species of rat snake that subdues its small prey by constriction.
Its docile nature, reluctance to bite, moderate adult size, attractive pattern, and comparatively simple care make it a popular pet snake.
