If I may ask - how did the kitten get rabies? And do they know for a fact that it was rabies? Did you and your family have to take anti rabies shots, since rabies could be transmitted thru something as simple as a scratch?
In Delaware if an animal is ONE DAY past due on a rabies shot, it will be quarantined, and if it hasn't had the vaccine at all and rabies is even remotely suspected, then it will be cage quarantined for 6 months! Believe me - I just went thru this less than 6 months ago.
