Sightings of the puma alife British "Beast of Bodmin Moor" apparently ceased after the skull of an Indian black panther was found near where a big cat apparently slew numerous sheep over the past several years. However, the apparent presence of a puma who mauled both a heifer and a dog in the Foret de Chize, France, in mid-May obliged the Prefecture des Deux-Svres to close the 13,000-acre forest to foot traffic. There is a zoo of about 600 animals in nearby Villiers-en-Bois, but no zoo cats have been reported missing.
