Is this woman a friend of yours?
Then forgive me for what I'm about to say, but it sounds like she is horribly under-equipped to be bringing home strays, if she has never heard of rabies! This is Canada! We have wild animals. We have rabies! You have got to live in a bubble if you live in this country and don't know about rabies.
When Horse Daughter brought home that half dead, straggly cat I was indeed concerned about rabies. I had my eye peeled for the first sign of neurological malfunction and that cat would have been hit on the head with a shovel and hauled in to the vet's for a RABIES test. Does that sound harsh? Rabies will kill you. 100%. Guaranteed. Dead. It is NOT something to fool around with and if you bring unknown animals into your home without knowing about rabies, you are a fool.
It sounds like this lady was not able to get help. BUt it also sounds like she did not utter the word 'rabies'. By her own admission, she didn't know about it. She has her own cats and doesn't know about rabies? HELLO!?! I suspect that had she phoned the vet and said, "we have a cat here that is showing classic symptoms of rabies, what is the protocol in this situation", she might have received attention. But she didn't say that. It would have been easy to treat her as just another lady with another sick cat. No biggy.
When I thought we had been exposed to a rabid bat, I phoned the poison control centre and told the man I think we had been exposed to a rabid bat, and how easily is rabies transmitted? He said, DO NOT MOVE FROM YOUR PHONE! Someone will call you in 20 minutes, and they did. After being thoroughly questioned, we had an answer. But they wanted to examine the bat's body, which we didn't have.
I know I sound hard hearted. But her family has been placed at serious risk because she has chosen to NOT EDUCATE HERSELF about the diseases one really needs to know about. I find that inexcusable. I would NEVER sit there and hope someone would come get the poor kitty. I'd be packing that thing in a bag and lugging it to the vet or RCMP. And then I'd get my family to an emergency room screaming RABIES at the top of my lungs! There is no excuse to not know.
