Not sure if the link posted to you. Several articles are out, just Google peanuts the squirrel. Apparently he bit one of the investigators.
At this time, there is only one way to determine if an animal has rabies if they havent' had the vaccine & that's to do a necropsy of the animals brain.

Thanks for the info and I have been in vet medicine for 30+ years and am aware of how to prep an animal for a rabies test
