Just after the server move the donation goal over at Ko-Fi was reached and I've just made the payment to my chosen charity: www.panthera.org
After looking at more than 2 dozen charities around tigers and wild cats, Panthera seemed the most fitting and trustworthy. They are fully dedicated to big cats and their entire focus is on their conservation. Their efforts are widespread, from supporting shelters to fighting poachers all the way to influencing legislation in countries where endangered big cats are at home.
Here's the donation confirmation :-)
