The Neumünster zoo in Schleswig-Holstein, Germany closed down on March 15th due to quarantine and lockdown measures from the coronavirus. Now the zoo is facing extreme financial hardship and may have to feed the animals to each other because they are unable to afford to buy food. Most zoos only operate off of donations and entry fees, and many are facing financial difficulty. The Neumünster zoo has 700 animals and has not received any emergency aid from the government. Zoo director Verena Kaspari commented that feeding the animals to each other would be a worse-case scenario, but she would do it if necessary.
