Where do I get squirrels?

I am terribly angry. Some people are hopelessly dumb. We have so many problems with coronavirus, and maybe it’s worth making conclusions and starting to behave differently with our planet? But no!
I will explain. Every spring, a nightmare begins. The villagers burn dry grass. It is forbidden by law, thousands of animals die with fire, but they continue to do so ... This year, the forest also began to burn ...
These baby squirrels are orphaned. It’s good that they survived. But now they will spend their whole lives in the aviary, because, fed by humans, they will not have the necessary skills to return to the wild.
