Can neutering an older cat stop roaming, fighting, and marking?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 1 year and 8 months old | 6.5 lbs

Hi, my Wilkie is 1 yrs old and he is still not neutered. Now, I've decided to neuter him because his roaming a lot of time than spending time inside the house. Sometimes, he likes to fight with other cats, and marking a lot of territory in our house, in and out. Will having neuter will make my cat's bad behavior disappeared???

Neutering will keep him from roaming as much although if he continues to go outside he may still fight with other cats. The urine marking in the house may stop but there is no guarantee as he is already older. If they are neutered young (like less than 6 months of age) then that behaviour is virtually non-existent. So, to answer your question......maybe some of the bad behaviours will stop but there is no guarantee. Regardless, it is better to have him neutered and I highly recommend it.
