Nope, not once, never.
I also don't know anyone who has witnessed this little mystery of nature.
Never in my life have I heard, "Hey! watch it! don't step in the squirrel crap!"
In 38 years, you'd think that at least once I'd have seen something that sets my mind at ease on this matter. But, no. Nothing.
As far as I'm concerned, women and squirrels just don't do it.
I also have never seen a dead squirrel that wasn't roadkill.
Nope, never seen a really old lookin squirrel, sprawled out in the 'last gasp' pose.
You know, diggin in the dirt, maybe got a little ringworm.
Maybe, got hold of some tainted cheese.
Could've choked, trying to impress her boyfriend with how many acorns she can hold in her cheeks.
Possibly even stepped on a bare spot while runnin across a power line.
But no, the only surefire way for squirrels to die is squirrelicide.
Poor little varment, no access to prozac, loses his desire for nut hunting, darts into traffic like a ninja. Jumping back and forth as if unable to decide to actually go through with it, until.......SPLAT.
I have my own theory theory though.
I think squirrels just eat and eat and eat, until they get so full that they just explode, POOOF!
