It she is healthy and there is no medical issues causing it then No. I’m my decades of experience if she has been sterilized and still sprays that is what she does. She will not stop. This is her instinct and she won’t stop. She needs to be an outdoor kitty with access to a safe (from predators and that she feels comfortable in) warm room/catio/shed to sleep in at night or to go to whenever she chooses. I’ve had many cats during the decades of my life and getting any sterilized cat to stop spraying is a losing battle. I’ve sought advice from animal behavioral specialists through those years and nothing worked. Through the years what I had always done is provide everything and then some to my kitties so that they are comfortable and happy. Most cats love being outside. I think in all my years I’ve only ever had 2 cats that didn’t like being outside…. It’s not common. All the best :)
