A ginger cat was found tied to a fence with a rope around her neck in addition to other injuries near Bristol.
Evie was found on Saturday [February 22] in Chessel Drive, in South Gloucestershire.
Her owner said she had been called by a local vet on Saturday to say her cat had been found dead by a member of the public.
A post-mortem revealed that she died from being hanged, but it was not possible to determine whether her other injuries were from being beaten, or self-inflicted in her desperation to escape.
Supporters of Holly Hedge have so far put up £1,000 reward for information leading to the name and/or conviction of the person or people involved.
People living around Charlton Hayes and Patchway areas are being urged to check any home CCTV monitors they have for Friday night into Saturday morning.
And are also being urged to keep a watch out for their pets.
