Rabies Vaccination in Recently Adopted Cat
I adopted a cat from a shelter two days ago. He's been really cuddly and just lounges around for the most part. However, last night there was an incident where he lunged at me and bit me. Following the attack, he chased after me and growled, and only stopped when my boyfriend came in from outside, startling him. The puncture wounds are pretty intense, and I've been cleaning them and keeping an eye on them. My concern, as irrational as it seems even to me, is about rabies. He was vaccinated on 3/20/13, but I'm wondering, if he had contracted it before getting the vaccine, if the vaccine would prevent him from transmitting it?
I'm sure that this sounds extremely paranoid, but I'd be very appreciative if anyone can share insight on the specifics of something like this.
