The owners of two cats who died after it is thought both were shot with an air rifle are offering a £500 reward for information leading to the successful prosecution of whoever is responsible.

Knebworth’s Sarah and Chris Unitt were devastated when their cat Leo was found dead in a garden last month, with blood on his fur.

Neighbours Nick and Juliet Cox found their cat Ziggy in a distressed state at their London Road home later that same week.

A vet found an air rifle pellet lodged in Ziggy’s flank and he had to be put down.

Sarah and Chris are now convinced Leo had also been shot and police enquiries are ongoing.

Sarah said: “A reward is offered in the sum of £500 for any information leading to the arrest and successful prosecution of those responsible for shooting and killing our cats.”
