In mid-2003 our house was granted the status of a European zoo according to the Brussels' criteria. The notification document Nr. MBA 6/7-M/A8890/02 encompasses 86 pages and regulates the keeping conditions for aquarium and terrarium animals, birds and monkeys. Certain renovations were necessary to comply with the new requirements. Additionally in 2002 the "Vienna Card" (which is an activity of Vienna Tourism) was introduced.
