These include three species of Mongoose (Herpestidae), classified as 11A/DS2 - southern wet temperate forests two species each of lesser cats (Felidae) and civets (Viverridae), one (Champion & Seth 1968). The sholas are confined to the species each of Otter and Marten (Mustelidae). They are Stripe- necked Mongoose Herpestes vitticollis, Brown Mongoose Herpestes sheltered valleys, while the mountain tops are occupied fuscus, Indian Grey Mongoose Herpestes edwardsii, Jungle Cat Felis by grasslands (Ranganathan 1938; Meher-Homji 1965; chaus, Leopard Cat Prionailurus bengalensis, Common Palm Civet Jose et al. 1994; Thomas & Palmer 2007). Of the 16 Paradoxurus hermaphrodites, Small Indian Civet Viverricula indica, Asian Small-clawed Otter Aonyx cinereus, and Nilgiri Marten Martes small carnivores of Western Ghats, all except the Honey gwatkinsii. It is interesting to note that the felines (lesser cats) are the Badger Mellivora capensis, are known to occur in Kerala more common small carnivores in the montane forests. Felis chaus was (Mudappa 2013; Nameer 2015); the small carnivore the most abundant small carnivore, which is followed by Prionailurus bengalensis and Herpestes vitticollis.
