Rabies in Buenos Aires? Highly doubtful. The last reported case of rabies in Buenos Aires was 2008 -- and previous to that they hadn't had any since 1981. That being said, the BATS in the city can carry the disease so if your crazy feral cat got it's hands on a bat it is possible
I wonder if the OP would have the balls to tell a vet to his face the various methods of torture that he tried to get the cat to leave.
Plus they are very alert on rabies here. I am currently undergoing an anti-rabies treatment because a stray cat I was trapping to sterilize bite me hard on the finger. The poor thing was scared, and I mishandled the situation. It was a cat I petted for months on the outside, but taken outside her environment and put in a room with walls and a ceiling set her crazy. At zoonosis they wanted me to take the cat back 5 times for observation, I have to take 5 shots of anti-rabies as precautions. The cat has not rabies, she would have been dead by now. She was just scared. But at the Zoonosis they were pretty serious about the whole stuff. Rabies is a thing they watch out for, and at the hospital I saw a few people people being vaccinated for rabies before me because they were bitten by random dogs.
I
do think, indeed, that you are a psycho.
First of all, you went chemical on the poor thing, and in the most cruel way possible. I wonder if this cat can see after you sprayed him/her with venom in the eyes, I can only imagine the pain and the scare you caused. Personally, I wouldn't sleep well at night if I did such a thing on another mammal.
Second, the cat was not attacking you, was not ruining your property, was not being a nuisance, so you going ballistic is entirely on you. You just met a cat in difficulty in your property, and decided to exterminate it.
Finally, I heavily doubt of your judgment because it is extremely clear that
you do not know cats at all. In fact, you can't even recognize a stray cat from a feral cat.
There is a huge difference between the two, and given the description you gave of the animal, and considering you are living in a city, it is most likely a stray cat. Stray cats are inoffensive, cats are the kinds of animals who manifest violence against humans only if attacked.
So please
STOP HURTING AND HARMING THE CAT, offer him a way out, let him rest so that he can take the jump and go away.
Have you considered the cat could be hurt because he fell on your property?!
I am still available to come and take the cat.
