Police have left a family "extremely frustrated" over their response to a loose dog charging inside a home and fatally mauling a cat.

Earlier this month (September 8), Vivien Tree, 67, was watching TV in her lounge when the cat – which belonged to her neighbour – fled inside before being brutally killed in front of her.

The force confirmed no arrests have been made and no dog has been seized.

She added: "We were told that support will be in touch, but it's been left and absolutely nothing has been done with it.

"It's extremely frustrating. I appreciate it's not a human but it's still a crime, this cannot be brushed under the carpet."

Vivien claimed Herts Police are yet to provide the victim with any update or aftercare.

A force spokesperson said: "Officers have been undertaking numerous enquiries, including visiting the address of concern.

"No dog has been located at this time and officers will be continuing their efforts to speak to those involved."

Anyone with information has been asked to report it via non-emergency number 101 or online, quoting reference 41/75004/24.

Reflecting on the ordeal, Vivien previously told the Watford Observer: “I’m absolutely horrified – petrified. That could have been a child, or it could have been me if I hadn’t of got out the house.

“I still see pictures now in my head of the poor cat there with his guts hanging out. It wasn’t just shaken, he’d had his guts ripped out.”

The 67-year-old recalled how there was “blood all over the carpet – its guts hanging out like a little massacre scene” when she returned inside, and the dog had left via the garden.

Posters showing an Akita dog - but not the specific one involved - have appeared in the area warning people to be wary as it "is not controlled or safely contained and frequently roams our streets on its own".
