A 5ft boa constrictor is on the loose after escaping from its home.
The public have been warned to look out for the pet snake that was reported missing from a house in Parbrook Road, Huyton, Liverpool, today.
Named Petzy, she is non-venomous but could be dangerous if she feels threatened, police said.
A Merseyside Police spokesman said: "The snake is a four-year-old boa constrictor. It is approximately 5ft long with black and green camouflage markings and yellow underneath.
"Whilst the snake is non-venomous and described as normally very placid, it may become aggressive if it feels threatened and the public are advised not to approach it but to contact Merseyside Police on the non-emergency 101 number."
