They don’t. My dog brought two infants to his dog bed. Found them in the woods when a nest was overturned after a storm. One died from internal injuries.
Hand fed the survivor. Cute. Had a cage built. Learned to get out....and out of the house through the dryer vent. Acorns kept showing up in my dirty clothes basket.
Would finally mature and would growl and bite when I would try to feed. Bye-bye.
Handed her over to a vet tech who lived in the country. We had cats.
Now I think of them as tree rats. They have screwed up our plumbing vents to the tune of several hundred dollars.
And I don’t brake for them anymore.
I figured out how to get ground squirrels from burrowing under the walkway: I pee into their hole every night.
I also got some pleasure shooting plastic bb’s at some tree squirrels. I counted 21 living in my neighbor’s Redwood tree — I’m sure there were more. Many of them moved elsewhere.
Squirrels know how to move on when they’re unwelcome. I enjoy hearing their warning calls when I walk by. A form of music in its own right.
