I am at my wits end. This thing is properly vicious, absolutely horrible (she's a Bengal and the vet said that they are renowned for being aggressive).
This cat stalks mine continually in the garden. She attacks nastily whenever she can.
It's now escalated because she's started coming into the house and attacking my cats in their home! She bit my kitten so hard on his tail the other week that he developed an abscess and he had to operated on under anaesthetic and had antibiotics for a week.
We can't have a cat flap (literally nowhere to put it) so I leave a small window ajar for my cats to get in and out. They've started messing in the house because I presume they're too scared to go outside (they have a litter tray but they've always been outdoor cats and they don't like using it). This is how the Bengal gets in and out. Obviously if I catch her in the house, I chase her off.
My neighbour is actually very good about the cat, if he hears a fight going on he will usually come and break it up, which I'm grateful for.
I know there's pretty much nothing I can do because cats are free roaming animals, but the situation is becoming untenable! So if anyone has any advice, it would be gratefully received.
