Hi
I live in south Northants. My husband and I have both seen on different occasions large black cats. He was fishing very early one morning when he saw a large black cat walk into the undergrowth at Iron stone quarry now a fishing lake off the A43.
Then I was going to work about 9am and saw a large black cat across a field at Stoke Bruerne the junction towards Blissworth.
Where abouts in Bedfordshire have you seen the big cats.
