My cat has seen the neighbor's dog through the window and started screaming, very nervous and scared. Had already happened other times, and I usually close the shutter interrupting the visual contact.
But today suddenly she has started screaming VERY loudly, and when I went to close the blinds she started to attack me, snorting and squealing, very angry. Quietly, and drawing that she was following me to keep attacking, I have managed to lock her in the bathroom, but she was scratching the door unabated and still screaming, as if she was suffering a lot of pain. After it had been quiet a bit, I went to look, but when she saw me she started screaming again, and I realized that she was releasing urine, I guess because of fear.
She has never acted this way. She is an eight years old spayed female, and never in her life has been aggressive and screaming.
What's the best option to deal with that?
