It's a private shelter organized by a young family in their country house. They have dogs and cats there.
When I'm in the countryside, I bring food and sometimes take pets to a vet. While I'm in Moscow, I transfer them some money (no doubt it will go to animals!) and post ads online to find owners for kittens and puppies <3.
(My own cat wouldn't like it, of course, but thankfully he doesn't know. He's very selfish :-D)
Aww, don't try to be useful - be helpful or generous. Working in an animal shelter surely is helpful; that's a good deed really. And of course there are some people who really cannot donate blood. That's not even required.Just let them donate who can!
What exactly do you do in the animal shelter, if I may ask?
Cheers!
