We adopted this badly injured baby squirrel. He fell from a nest and was most likely attacked by some birds.
His left eye was hurt pretty bad. My grandmother found him and first thought he was dead but he moved faintly when she was going to move him out of the road so she put him in a small cardboard box, called me and asked if I could take care of him.
We contacted a couple of rehabilitation places here in Finland but none of them could take him at the time. They gave us some info about what we should feed him and such - pine cones, nuts, fruits, berries and mushrooms.
When it seemed like he had recovered, we tried to release him back to the wild but he fell from a tree and hit a rock. He survived, but we realized that his eye would never heal completely and he wouldn't survive on his own.
So we kept him and named him "Arttu."
We were very surprised how tame he became. He liked to have playful "fights" with our hands and he was smart enough not to bite too hard. He also liked to take naps in our pockets. He even recognized his "family" and became very wary if there were strangers nearby.
