With nearly 4,000 species from which to choose, snake fans can easily find a pet to suit their interests and level of experience. The captive breeding of snakes has exploded in the recent past, with species once rare in zoos now common in neighborhood pet stores. Folks put off by providing rodents as food (now readily available pre-frozen) can choose from captive-bred insect or fish-eating snakes. The care of many species is well-known, yet there are hundreds of others whose secrets remain to be uncovered by experienced, serious keepers.
