Rabies is a worldwide issue - except a couple of islands Australia, NZ, Br Isles, Hawaii
All mammals are susceptible
Transmitted thru the bite of an infected animal
in the US fox, skunks, racoons and bats primarily (although there is a report of a rqabid squirrel (if I recall correctly) infecting a guinea pig on a lawn! There is a geographic distribution for the various animals that transmit rabies - ie in the "thumb" of MI there is skunk rabies, racoon rabies like I described etc bats pretty much everywhere
rabies in cattle
incubation varies from 2 weeks to months (that is the time from the bite to symptoms)
Bizarre mental behavior, yawning, hypersensitive, belligerant, difficulty swallowing, incoordination, drooling, decreased sensation in hind quarters, recumbancy, death - any abnormal behavior that could be neurological in origin - always rule out rabies
what state are you in? I'll bet that caused quite a stir! There are specific guidelines for human vaccination after exposure - hope that helps some,
