Why is my cat suddenly aggressive towards me in our new apartment?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 12 lbs

So I have separated my cats due to aggression at my new apartment. However, Molly, who is in my room, has become aggressive towards me! She attacked me for no reason while I was sitting and talking on the phone. I had to spray her with water to stop her, and put her in a crate! At the moment we only have one litter box, the other is still at the old place. I can't lock her in the bathroom or the other will lose litter box access. I am at a loss. I don't know what's wrong.

It sounds like Molly may be reacting to your other cat even though it is not in the room. This can be scary since it is usually uninhibited aggression. You have to do what is necessary to stay safe (spraying with water or covering her with a towel) but keep in mind that punishment can make the situation worse by causing fear. If you don't already have pheromone diffusers like Feliway in the house I would definitely recommend getting some, and I think it sounds like you need a second litter box for awhile. You may want to consider talking to a behaviorist to try to determine how your cats can live together - your veterinarian should be able to give you some names.
