mongoose Facts. Although they appear remarkably similar to weasels in form and lifestyle, mongooses are actually members of the superfamily feliforma, or cat-like carnivores, while weasels are in the superfamily caniforma or dog-like carnivores.
Mongooses also have receptors for acetylcholine that, like the receptors in snakes, are shaped so it is impossible for snake neurotoxin venom to attach to them. Mongooses are one of four known mammalian species which possess mutations in the nicotinic acetylcholine receptor that protect against snake venom.ongooses range in weight from the common dwarf mongoose, at 320 g (11 oz), to the cat-sized white-tailed mongoose, at 5 kg (11 lb).
