Why is my cat suddenly aggressive after her housemate had a bath?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 2 years and 3 months old | 12 lbs

I have 2 cats. Yesterday one of them got dirty and I had to give them a bath. Since then, my other cat hisses or growls whenever the cat I washed comes near. Why is she showing sudden aggression? And what can I do to help?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly because she smells differently. I recommend a product called Feliway which can help decrease stress and anxiety associated with environmental changes and stressors. You may find this online or at your local pet store. It usually works great in this type of scenarios. Good luck and have a great day!
