Big cats do exist and there is evidence to prove it - that's the message a Plymouth-based organisation will give to Downing Street later this year.
The British Big Cats Society (BBCS) says it has "strong and convincing evidence" to prove the existence of the wild beasts, and will present it to Number 10 in August.
The document, which includes details of video footage, foot prints and hair samples, will be handed over in a bid to convince sceptics that the big cats do exists.
Danny Bamping, founder of the society, said: "The document is a run down of all the conclusive evidence we have evaluated over the last three years. Our aim is to prove their existence and protect the cats. This document will satisfy one of those aims - it will prove they exist."
The BBCS is also currently identifying the body of an exotic cat found in the south-east of England.
During the last year, the society has received six new clips of video footage showing big cat sightings from across Britain. It also says there has been three confirmed attacks on horses and two on humans.
After being handed over to Downing Street, the new evidence will be given to the Department for Environment, Food and Rural Affairs (Defra) and the police.
A Defra spokesman said: "We are looking forward to receiving this evidence. We only get involved when the issue concerns the farming community and the welfare of their livestock.
"Most of our work is with farmed animals not wild ones. However if someone wants to send us evidence we will take it seriously."
Devon and Cornwall is classed as a big cat hot spot and Bodmin Moor is one of the most famous places in country for big cat sightings.
The first "Beast of Bodmin" sighting was recorded in 1983, and since then more people who claim to have seen the puma-like animal have come forward.
In a report released by the BBCS, the number of sightings in Devon rose from ten in 2001 to 97 in 2002.
In Cornwall, there was an increase from seven in 2001 to 44 last year.
Farmers in Devon and Cornwall blame the big cats for killing dozens of livestock - particularly sheep.
And in 1994 the Government realised the reality of the problem and carried out an investigation on Bodmin Moor.
The Defra spokesman added: "We carried out the investigation but found no conclusive evidence to suggest they exist. Since then no one has presented any evidence, so we look forward to receiving this document."
The report will also reveal a number of possible ideas explaining where the cats have come from.
One explanation is thought to date back to the 1970s and 80s when new legislation forced exotic pet owners to set their animals free. Releasing these wild creatures into the British countryside was legal then.
Mr Bamping said: "The society believes this document will help enlighten the relevant authorities, and hopes it will encourage the undertaking of an official study into their presence in Britain."
The BBCS is also calling for anyone who has had an encounter with a big cat to report it on their website at
