My cat is jealous of new cat, hisses at me. How to stop aggression?

Updated On September 23rd, 2025

Pet's info: Cat | Persian | Female | unspayed

My cat June was a loving cat and was very attached with me. But since we got a new cat, she has been displaying signs of jealousy. She hisses and attacks Molly, even hisses at me when I try to hold her. I give them as much time as I can, treat them equally but her behaviour is not improving. If theres an effective way to resolve this situation please let me know.

This is not uncommon, cats are not naturally sociable and take time to accept new cats into the territory. Pheromone products and calming supplements or diets such as royal canin calm can be very helpful
