Alligators have been found roaming Pittsburgh on several occasions in the last year, and there is now a push to ban the sale and ownership of reptiles in the city. City Councilman Bruce Kraus introduced a bill on Tuesday. It would ban businesses and residents from selling, owning, adopting or exchanging turtles, alligators and crocodiles. Snakes would still be allowed. If caught violating the ban, people would be fined $1,000 for each reptile and could face jail time. Kraus’ proposed legislation would repeal an ordinance passed by city council last year that permitted the ownership of crocodiles, alligators and snakes, with restrictions such as having to keep them in containers or boxes at all times. But Kraus and animal rights groups said the prior ordinance was inhumane.
