A few years ago, anyone who reported seeing a "big cat" roaming the countryside would have been the butt of pub jokes.They would have been told they were imagining things, had simply seen a domestic cat, fox or some other familiar animal under difficult lighting conditions - or, more frankly, that they were lying.Today, however, that attitude is gradually changing - thanks mainly to the work of the Dartmoor-based British Big Cats Society (BBCS), whose twin aims - to "prove and protect" - are to establish beyond all reasonable doubt that exotic felines really do roam our countryside and prevent them from being shot on sight.A staggering 1,077 sightings were reported in 2002 alone, plus a further 679 sightings from previous years. Scotland was the leading hotspot with 209 reports, followed by Devon with 97, Kent with 92 and Wales with 86.Now in its fourth year, the BBCS strongly believes that this is only the tip of the iceberg, that big cats are being seen much more often than was previously thought. Society officials estimate that for every sighting made public, a further three or four are never reported.Last year was an "extraordinary year," according to BBCS founder Danny Bamping, a 29-year-old wildlife cameraman based in Plymouth. Figures for 2003 are to be published at the end of this month and data collected have been vast, due to the number of external contributors, such as the National Farmers' Union (NFU) RSPCA, wildlife trusts, several police forces and the Department for Environment, Food and Rural Affairs (Defra).Bamping, who has been investigating the big cats of Britain for 10 years, says he is delighted with the fact that Defra invited the BBCS to give a presentation on big cats last month - "Several DEFRA employees came forward and disclosed their own sightings" - and that the NFU has pledged its support for the society's work.
