Why is my 9-month-old male cat spraying before he's neutered?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | unneutered | 4 lbs

My cat is 9 months old, male. Recently i found him urinating on horizontal surfaces like plastics, and there was a pool of it. I thought maybe it is my fault because he is very particular about his litter. Then again today he was being very vocal, jumped on my vanity and sprayed on my stuff (little). i also caught him trying to urinate on plastic bagagain. His second vaccination will be on 17 dec, and for spaying 2 weeks after second vaccination. Should i keep him isolated until he is spayed?

Intact male cats often spray in the home due to elevated testosterone. Instead of isolating him, which will only make him more anxious and likely to spray more, I would suggest getting him on anti-anxiety medication through your vet. Fluoxetine can work well for cats that spray in the home and can be used up 1-2 months after his neuter, which is the typical time it takes for all the testosterone to diminish in the body. You can also consider moving him neuter surgery to an earlier date. I hope this helps and best of luck getting Mochi to stop spraying in the home. Take care.

    I'm sorry to hear that your pet is spraying. Unfortunately intact male cats will almost always spray in the home b/c they are marking their territory due to the high testosterone levels in their bloodstream. You will need to get him neutered to stop this behavior. You can ask your vet for some medication (i.e. Prozac) to give him until you can get him scheduled to get fixed. This worked almost instantly for my own cat! : ) This mediation works in many cases to stop the spraying, but for a long term fix he will need to get neutered. Thanks for visiting Petco Pet Education Center, formerly Petcoach and best of luck with Jack moving forward! Take care.
