ICYMI: The squirrel reacts to "´mpt her", a German shortcut of "Kommt her!", "Come here!". It was still a bit nervous (no straight line), but came after advising it to come to get a nut without fearing anything.
Is this animal my pet?
I feed it (partially/for fun).
I call it.
It reacts to me.
It trusts me.
We communicate in a special way.
