The Visayan leopard cat (Prionailurus bengalensis rabori) is a leopard cat subspecies described in 1997 on the basis of morphological analysis of a skin and skull collected in Negros.^[2] It is endemic to the Philippine Islands of Negros, Cebu and Panay, and has been listed as Vulnerable on the IUCN Red List since 2008 as its range is estimated to be less than 20,000 km² (7,700 sq mi).^[1]

It is probably locally extinct or close to extinction on Cebu and Masbate, and persists foremost on Panay and Negro, both of which have lost 90–95 % of their natural habitat.^[3]

Characteristics

The fur of the Visayan leopard cat is dark ochre to buffy fawn with large and dark spots. Its skull is a little narrower than of Sumatran leopard cat and Bornean leopard cat.^[2]

Distribution and habitat

In Panay, it is survives in the remaining forest fragments of Northwest and Central Panay Mountain Range which includes Lambunao, Calinog and Bingawan in Iloilo, Tapaz in Capiz and Tibiao, Laua-an and Barbaza in Antique. It was also reported in Sicogon, Carles, Iloilo an island off the northeast coast of Iloilo. In Negros, it was reported in the forests of the North Negros Natural Park, Mt. Kanlaon National Park, and Mt. Talinis-Twin Lakes Natural Park. Is likely to be found also in forest fragments of southern Negros Occidental. It also inhabits sugarcane farms. In Cebu, it was reported extant in only two areas, Barangays San Jose and Santican in Catmon.^[1]

All available data - including former (i.e. late Pleistocene) land bridges connecting all the West Visayan as a single land mass), coupled with its recent known distribution and these animal’s evident tolerance to a wide variety of habitat types – suggest that leopard cats were formerly widely distributed through the ‘West Visayan (or ‘Negros-Panay’) Faunal Region’, and have therefore been extirpated from at least 90-95% of their presumed former range and are still declining. The West Visayas has also suffered the worst rates of deforestation within the Philippines, wherein total forest cover has been reduced to less than 180,000 ha and 4 (of the 6) main islands now have less than 0.01% remaining forest cover. What little forest remains is also highly fragmented, often degraded and usually subject to further attrition and other disturbances through the illegal collection of timber and other forest products. Hunting pressure poses an additional serious threat in some areas, and although leopard cats are seldom specifically targeted by hunters, they are frequently ensnared in traps set for other species and/or captured on an opportunistic basis. Outlying subpopulations inhabiting sugar cane farms in primary sugar areas on Negros Occidental, are also subject to opportunistic hunting pressure (especially during can harvesting) or probable widespread use of rodenticides and other agro-poisons.

Kitten mortality due to habitat loss

It is clear that the Visayan leopard cat mothers frequently and gives birth in sugar cane fields, presumably attracted by dense cover and an ample supply of rats and other agricultural pests. It is not clear whether pregnant cats migrate into the cane fields from neighboring forest patches to give birth, or whether they permanently inhabit agricultural areas. In either case, the harvesting of sugar cane has disastrous consequences for any females rearing litters, which they are then forced to abandon.

Most kittens orphaned in this way die before or shortly after they reach rescue centers, probably from dehydration or other factors relating to their age and the length of time between their capture and arrival at the center, which can be several days. Improved personnel training, access to expert advice, better equipment, better milk substitutes, and imported vaccines all can contribute to improving the kittens' chances of survival. Rescued kittens almost certainly represent the only captive stock, though even this number of individuals is now putting a severe strain on available resources.
