In the last decade, keeping special pets such as snakes, tarantulas, alligators, monkeys, and even scorpions has become very common in Iranian houses. Unlike domestic pets such as dogs, these animals do not need to go outside the house and they are kept in the closed apartment spaces. Due to the increasing demand for buying various pets, a large underground network has been created to buy and sell animals, and keeping pets has become a strong culture and economy in Iran.
