Mongoose is also effective against habu (native snake of Okinawa) but these are NOT people friendly critters. Taming one would require as much effort as taming a wolf or cougar. They were used as killing machines in caged paid for carnival midway's on the military bases in the 60s. It usually took 4 or maybe 5 snakes to put the mongoose down for good, but by then the snake was always dead. Dead snake, no problem we got more snakes in the cages, dead mongoose, no problem we got more mongoose in the cages. No winners here, not the critters nor the ghouls paying to see this exibition of death. Mongoose is not house pet material but maybe out in the woods nearby they would be just fine as a natural snake supressor.
