Police officers were called to rescue a cat which got her head stuck in a jam jar trying to catch a mouse.
A motorist found the tabby wandering beside a road in Peterborough, Cambs, with the jar on her head and the mouse millimetres from her nose.
The officer pulled and twisted but could not release the cat, and the animal eventually freed herself and the mouse by smashing the jar.
"It was like a scene from Tom and Jerry," a police spokeswoman said.
The motorist had taken the cat, mouse and jar into Thorpe Wood police station where three police officers were asked to help.
The spokeswoman said: "They tried to prise the jar off as this terrified mouse looked on - but it was firmly wedged. Eventually the cat smashed the jar on the floor and the mouse ran off - it's still running around Thorpe Wood police station somewhere."
The cat, called Mindy, was found to be microchipped and was quickly reunited with her owner in Peterborough.
She was examined by a vet and found to be unharmed.
