Dan- It is serious with the rabies, but they only do 10-14 days anymore. I had one of my cats reported after a month long killing spree..2 possums, a wood chuck, numerous squirrel and other rodents, rabbits, & 3 Copperheads...Best Cat ever!!! We call him the Honey Badger, cause he doesn't give a shit. The goldens would just roll in the dead carcasses. But I had a neighbor report him and animal control had us quarantine him for 10-14 days can't remember. Good luck...and give them a couple extra treats for that one.
