We feed squirrels here --- we all have squirrel feeders in our yards.
We do to and can't keep those danged birds away from them.
I feed squirrels indirectly - I have a large walnut tree that attracts the furry devils from miles around.
It seems 2 tribes of squirrels would visit the tree at different periods throughout the day with the leaders fighting for browsing rights.
They litter the yard and walk with nut shells, then they travel on the overhead power lines to avoid the dogs.
