Personal
Some causes I believe in and donate to:
Ukraine https://war.ukraine.ua/donate/
Myanmar resistance: Unfortunately I rarely end up using the same link twice but you can read up on the conflict and ask your friends from Myanmar which links they use on r/myanmar for example.
Vucjak shelter : A wonderful man from Serbia who is actively caring about some 1600 dogs and cats and constantly needs help.
Cool critters: A shelter in Czech republic doing some wonderful work, I got my cats from there as well! They always need fosterers for their animals.
MY CATS! Nićifor (Standard issue grandma cat) and Quentin (Black)
