Relax. Rabies dies quickly outside of a body. If the fox is cold and stiff, the virus is long gone. Wear gloves anyway, because dead things are gross, and you don’t want tetanus either.
Also, no, you can’t get rabies from a scratch unless the scratch had infected saliva on it. So if a stray cat scratches you, wash it well and keep an eye on the cat. If the cat is fine in 10 days, you’re fine.
