Leaving your cat alone to get over the feelings of aggression is the best bet to ensure that there is no unintended altercation between you and your pet. You should also try to segregate the cat from any other pets or humans in the house.
This should hopefully cause your cat to stop paying attention to whatever it is that is agitating it and give the cat an opportunity to calm down. If you use water, keep a spray bottle readily available.
If you have to engage with an aggressive cat, take the proper safety precautions. Wear thick gloves if possible or several layers of clothing. Try to avoid separating your cat from another animal if it is behaving aggressively. But if you must interfere, be extremely careful and be cautious of bites and scratches. Try using a squirt bottle or pillow to break up a fight between cats. Remember that it is possible for the cat to injure itself also. Try to control the cat’s behavior without provoking it to react in a way that is more harmful to itself. If you do get bit or scratched by a cat, go to a doctor right away to have it treated and looked at. Even if it seems superficial and not serious, cats’ mouths have lots of bacteria and can cause very severe infections that can become systemic if not treated.
Try covering the windows with blinds or curtains, preferably ones your cat can’t simply push out of the way. Remember to leave the door closed so that your cat can’t constantly look out of the screen. Additionally, you can try closing the doors to rooms that provide views of the outdoors.
After the cats have been separated for a while (at least a few days), start introducing them to one another again slowly. Start with a smell introduction, where you bring in something that smells like the other cat. Then move toward a short face-to-face encounter. Keep lengthening the amount of time you keep the cats together until you think they’re ready to be around each other full time again.
If you must engage with other animals, try to wash your hands or change clothing before you see your cat at home.
This doesn’t indicate that your cat is mean, doesn’t like you, or that you have a bad relationship with your cat.
Start by talking to your cat’s veterinarian, who may be able to offer a referral. Otherwise, search for an animal behaviorist in your area.
