Valerie Rodrigues was on her way back from Redbourn at about 8.30pm on June 6 when she spotted an animal dart out into the road in front of her car.
At first she dismissed it as a fox - it was a “gingery, sandy colour” she said, a similar size, and trotting - but as the car got closer it started to bound away.
She is now “absolutely sure” it was feline: “It was definitely a cat in the way it moved, in its well-defined muscles in its legs.
“Cats don’t run like dogs or foxes, they are more arched in their backs. I don’t doubt it was the cat.
“If it hadn’t run I might not have quite realised what it was.”
